Al-  Try going with Comp Cams, somewhere about 280 degrees duration.  I am running a solid roller 292 in a 454 with rect. port  heads.  I ran a 292 flat tappet in an oval port motor a few years ago with good success, but don't want to lead you on.  It had decent low end and pulled hard up high, probably more than needed. My book does not touch on your heads.  What are they?  I was working with large oval ports, mildly touched up.  Those combined with a 427 with 3/8 rods and about 11:1 compression put me at solid 13.3s in the quarter with a close ratio muncie and 4.56 gears on slicks.  Should have done much better.  Clutch was slipping bad once slicks went on.

Subject: Re: [Chevelle-list] are these heads ok heads casting#14092360+454 build up

Are the stock pistons ok? If so,why not keep them and spend the money on some good headwork or even some World Merlin oval port heads,instead? If it were me doing the build-up,I would try to stay away from compression ratios that require premium fuel. The difference between a 9:1 and 10:1 compression ratio is probably less than 20hp/20ft lbs tq.
Tell us more about your combination. What transmission will you be using? What rear gear?
Not familiar with those #360 head castings. Can anyone offer their input?

Well the wife gave me the ok to rebuild the 454 I want to get as much hp as possible will be going with Forged Dome, 4.250 or a little more in 10to1 or better I would like to go with a  Lunati Voodoo Cam or some thing similar (((looking for some suggestions))) any help would be great especially with some one that has done a 454 build up before. I am trying to save some guess work. I am no stranger to building engines. I would like to get the right combo the first time around if you know what I mean.
can I get 400 to 500 hp out of these heads casting #14092360 I am rebuilding my 454 and the budget does not allow for replacement heads yet. thanks for your input.
