Will,

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 heads without flow numbers, so I'm not expecting anyone else to, either.

FLOW NUMBERS

I had two heads flowed.

Lift      #1 Int    #2 Int
0.100     58.7      58.0
0.200     110.5     110.8
0.300     135.7     138.6
0.400     145.0     142.1
0.500     149.5     151.0
0.600     151.0     152.5

Lift      #1 Exh    #2 Exh
0.100     56.9      58.4
0.200     101.9     100.2
0.300     140.0     138.2
0.400     149.0     152.1
0.500     152.2     153.6
0.600     153.7     153.6

I find this data very interesting. While the peak numbers are less than I was hoping, the mid-lift numbers are marvelous.
These heads waste no time getting a big fraction of their flow going once the valve lifts. I think it's obvious that's what BPE was going for when they did this port work.
It's also very interesting that the exhaust flow is approximately the same as intake flow. This indicates that the engines on which these heads were used had very high compression.

This will be better than stock heads on a built engine, but they will REALLY shine when used with a blower or other form of forced induction.

A multi-angle valve job would probably provide significant improvement. I didn't have the scratch or time to have one done on this pair before getting the measurements done. The seats in these heads were last run in race engines over a decade ago, so they could benefit from cleanup work.

For those ready to buy, the best way would be via paypal to william.lucke@highspeedlink.net .

I'll let the titanium retainers go at $100/set (set being enough for an engine) and the rocker studs go for $50/set.
Heads are $400/pair and Titanium valves $200/set.

These numbers are from Oreif on PFF who had a stock head and a ported head flowed to see the difference. The "stock" head may have had a cleanup, I've heard both about this data.

The Falconer heads beat these at low lift and at every exhaust lift point. The Falconer heads only give ground at the highest intake lift.

As I said before, the valve job on the Falconer heads was raced on 10 or 15 years ago. A multi-angle valve job should show noticeable improvement at all lift points.

These heads were used on engines that made 300 HP naturally aspirated back in the day. They would do well in any iron head V6 buildup. Modern roller cam technology can take even better advantage of their capabilities.
