Remember many of these heads are on 4.100 or bigger bores.
It is currently 4.185" bore. But it's got some wear on it. I'm going to get it sonic checked. If it'll go 4.220 I think that's what I'm going to do.Remember many of these heads are on 4.100 or bigger bores.

I don't think that he has put them on the flow bench yet.What size bore did Brett flow test them on.

I ran a 2.100 valve on a 4.04 bore. That's right at 52% of bore diameter.
I run a 2.08 valve on a 4.030 bore and use a 4.015 bore on my flowbench.
That's about 51.65% of bore diameter. about as close as you can get to 52% without being exactly 52%.
Pretty spanky.
Too be honest with you. I don't understand all of the dynamics. As explained to me. It has something to do with emptying the cylinder. But that's what I was informed. I guess we'll see.I can’t see how a cam is good for one fuel and not another.
Compression ratio - sure.
Brett said that the ports sounded really good when he checked them. Larry Smith did the porting. Brett was very complimentary of his work.

Yeah, you guys are both good guys in my book.I always did like that guy 80% of the time. I’m not an easy guy to like because I speak my piece, and so does he.
I understand Top Fuel is totally different, but they have to open the exhaust valve vary late cause the pressure so high it would destroy the valvetrain if they tried to open it early. Not saying this is what's happening with alcohol but image there could be some effect the cam has to compensate for.I can’t see how a cam is good for one fuel and not another.

Maybe you guys can have a 3 way group hug. lol
