too small
Those heads aren't even close for a 632", ..
the valve angle, chamber, portshape all make that a good head
for something 540" or smaller, .. but won't even come close
to hanging with current technology heads for big inch engines, ..
doubt you'd make close to 1000hp with them, .
Fully ported on my honest flow bench that head will flow about
430 cfm @ .9", .. FULLY ported with a 50* VJ, ..
I'm not really a fan of the Brodix oval ports unless you choose the largest
on they make, .. reason is the oval opening drives airspeed too
high, it's like using a head that's too small.

The point was, he has these heads. He plans on running them. Everyone is so quick to junk what they have, to buy something else, when what they have will work, for what they are trying to do. Are those heads right for a 632, no, I already said that, IF your trying to make the most power possible, or go heads up racing. But, with a bit of work, will make a lot of power. How much power does he want, is the real question. If he says 1000 easy hp, then no, they won;t be right, and he would be better off with something else. If he shruggs his shoulders, and says, what ever it will make, then, they will work, and, he already has them. Not every guy on the planet is trying to be top dog. A mid 9 or low nine second bracket car, is a heck of a fun ride. That was my point. With the right cam, and compression, ported with decent, not all out port job, that combo could make 900hp. It would make brutal tq, which, could be an issue for traction, but otherwise, at 2700lbs, 900hp is easily enough to run way into the 8's. Is that fast enough?

Thanks mate that was my point.I have these heads and i wanna know how to make them work well and if they have worked well in the past.I know these are not the best heads to use for a 632 but thats all ive got to work with I am on a pretty tight budget being age 23 with a 632 Bracket car and no sponsers so every single doller that is used has to come out of my back pocket.Thanks for seeing my point.A mid to low nine will do me just fine and theres always going to be room to play with later on down the track.

IMO a lot we make over 1000hp with 565's and bb3 oval ports, 1050 on 582's

All the vehicles i mentioned run S/BLKS, and what ever your goal is it will be a fun run when it hit's the track.
