EDIT: DO NOT CALL FALCONER ABOUT THESE HEADS. Eric sold them to me to be rid of them. He does not have the time to field questions about them. Ask me what you want to know. I will have flow numbers soon. The shop tells me within a day or two. Once I post those numbers, I will start accepting money. I wouldn't want to buy ported heads without flow numbers, and I don't expect anyone else to, either. [/edit]
I will shortly have a lot of 19 iron heads of the type used in the 60 degree 6 racing effort in the late '80's. These are the heads used by Falconer on their 280 HP 2.8's and 300 HP 3.0's. That's 100 HP/Litre from naturally aspirated 60 degree V6's! The port work was done by BPE ( www.bpeheads.com ). Falconer ran 1.720 intake valves and 1.430 exhaust valves. I am currently trying to track down flow numbers, but these were done a long time ago and not everyone keeps extensive records for 20 years. I am told they were run in competition with approximately 0.560 lift. They are physically capable of 0.600, but there's no gain beyond 0.560.
These heads are USED race heads that are in serviceable condition. These are NOT fully assembled, ready to run parts. Most are bare castings. I am told that several of them need seat clean-up and some of them may need more work, like guides.
Delivery is scheduled for this Thursday. They are coming by truck. A 715# pallet is hard to ship... I'll have weight and shipping cost information shortly thereafter. This weekend I'll try to get one to the shop that's doing my N* block in order to get some flow numbers.

Spoke with the shop. They'll be able to flow a head middle or late next week (25th or 26th). They were a bit busy this week. One of the Efantis's blew an engine last weekend and needed a new one for next weekend.
I got pushed back, too. My N* block was next up when they had to drop everything and build that dam 2JZ.

I received a pleasant surprise this afternoon... a pallet full of cylinder heads arrived.
It carried: 23 iron heads (20 ported, 2 cracked, 1 stock) 3 aluminum heads (2 with rectangular ports, one with trapezoidal ports) 24 pushrod guide plates 47 large rocker studs 12 small rocker studs 23 titanium intake valves 24 titanium exhaust valves 37 triple wound (or is it properly called dual w/ damper?) valvesprings 49 titanium retainers for small keepers 12 titanium retainers for large keepers 48 pr small keepers 12 pr large keepers 5 springs seats & associated parts
Pics to follow. I will be taking a head and a pair of valves, springs and retainers to a shop next Monday. I'll have the head flowed and the spring measured.
In terms of sets, I have: 10 workable pairs of iron heads (putting 8 up for sale) 1 cracked pair of iron heads 1 stock head casting almost 4 sets of 7/16" rocker studs (just missing 1) 1 set of 3/8" rocker studs almost 4 sets of Titaium valves (missing 1 intake valve) Putting 2 sets up for sale 3 sets of springs + a spare 5 sets of titanium retainers & steel keepers (4 sets + spare for small keepers, 1 set for large keepers) 4 sets of pushrod guide plates almost one head's worth of spring seats.

On the deck and chambers pic, you can see cutting marks from a very large diameter head. I'd say that this is the factory deck surface on this particular head.
Falconer is definitely on the west coast... Heads came with no rust-preventative measures taken but were rust free. They sat here for a week and already had surface rust. I used a whole can of WD-40 thoroughly spraying down ALL of them. This one is one of the worst and it's not very bad... I caught things in time.

I find it interesting that Falconer removed the "shark fins" from the intake ports, in contrast to the Chevy Power book which specifically says "Don't...".
Not to imply that Falconer doesn't know what works on his heads. Just interesting.

I was going to post the same thing, but didnt want to turn this into another V-6 2.slooow debate. Not all books are the gospel. (you turbo guys ) I think a obstruction in air flow is still a obstruction, looks like Falconer agrees.

The Chevy Power book may also be written with an eye toward DIY or mild head porting. These heads have neither. There is flow bench development behind them. I would guess that since the fin was removed, it was beneficial to do so.

Unfortunately, I have to officially drop out as I delivered my heads to the machine shop on Saturday.
However, I will be sufficiently jealous if ANYONE of you dynos higher than me. You've been warned.
Not trying to be a smart a$$ but if you don't know. It's not about how much you can flow....It's about velocity. If you port the heads to enlarge the area to get more flow you will suffer low end horses and torque. But if your force feeding the engine then it doesn't make much of a difference. Just tryin to help if you did'nt know.
And also a free bump^^^^

There's a continuum of port size for any engine. It's not as simple as "gain flow, lose velocity"... what if the gains in flow are much greater than the losses in velocity? If the port was WAY too small and saturated during the entire intake event, then you'd likely see a huge gain in flow with only a marginal decrease in velocity over the duration of the valve event.

I can't wait to see how some of these heads run on a 3.4. Now if there was only some way to get the Fiero intake to flow enough to feed them. To me, keeping the original look is the primary reason to go with the 3.4 iron head. Once it doesn't look original anymore, might as well go with a Gen III setup and get roller cam and rockers, better heads, etc. That or a 3800SC, etc.
A 200+ HP normally aspirated 3.4 that still looks like the original Fiero engine. That would rock.
I decided to call Falconer racing to see what they said about the heads, specifically the removal of the vane in the intake port. Ryan was not in the office, but his son Eric was. He told me that anything done to the heads was for more power. He said if I was going for all out racing I wouldn't get anything better as far as the iron heads go. I still would like to see the flow data to confirm this.

We have a problem here. I just got a call from a guy who saw the heads on the internet you are selling. I can not take the time to field calls from anyone who has questions about the heads. Please do whatever you have to in your listings to tell these people NOT to call here. We're way too busy.
Sincerely,
Erik
DO NOT CALL FALCONER. He sold these heads to me to be rid of them. As the email says, the last thing he needs right now is people calling him about these heads. DEAL WITH ME.
I don't want to keep these heads any longer than I have to. Trust me, when I have the flow numbers on them, I will post them here. Once that information is up, I will start accepting money. I wouldn't want to buy ported heads without flow numbers, so I'm not expecting anyone else to, either.

I guess we were posting at the same time. So we got to the bottom of that... As you can see from my message above, he doesn't want to field calls about these heads. Re-read my initial post. Falconer built the engines, Falconer sold me the heads. The port work was done by BPE, not Falconer.
