What does the other side of the head look like??

I would pass as well, gotta keep at least ONE ace up yer sleeve
Well, there's clearly two routs about .525 deep.
Now if we can get a good look at the pistons, we might be able to figure it out.
Rex, Tman, I don't think I want to play poker with this guy . . . .
Haha! It's not that big a secret- think modified Harley KR/Navarro heads, with popup flat tops.
Dr Goggles, Jimmy- In BVGCC we will have a bellypan, and in BVGALT, we
will have a step pan, so both will act as a 'skidplate.
Jimmy, remember, BVGC is no longer an option, with 14% setback.
Tom, I can't remember the new base circle, but the small diameter is
now 1". Stock was 1.375"
Littleliner, that's the one!
Ok, I received the preliminary stock flow numbers from Joe Abbin. These
numbers are with stock valves, no port work, and our custom chamber
head. Next up is port work, valve guide relief, and a 1.76" exhaust
valve. we will test both a 1.94" and a 2.02" intake valve.
Dale and I were chatting, and so far, it seems that if you look at the graphs, it sure looks to be very port constricted. On both the intake and the exhaust the amount of additional CFM that it flows between
.278 and .500 drops off drastically. In effect, you can raise the valve just
about all you want and it just doesn't matter all that much. This is why
getting the valve open early and keeping it open (duration), a blower and
porting will be very big components of horsepower.
From looking at the block, doing extensive work in the bowls, short-side radius,
etc - should make a big difference. My guess is that the overall size of the
port won't be the limiting factor (up by the intake manifold), but what happens
when the ports turn and get constricted into the bowl and the overall size of
the bowl area.
While these numbers are laughable by OHV standards, they excite the hell out of me! They show 20-25% more flow than a stock Ford, according to Joe Abbins flow bench tests.
So, we're off to a very good start!
