Thanks Greg, I am just about going to have to stay with the 572-13 heads.Having to buy a set of B1MC heads would take away to much of my $$$ and not leave enough to do much else.But might look into the Ti. intake valves. I already have a tunnel-Ram to use and will run alcohol,gas may be as good but I'm a Bracket-Racer and have to run the alcohol to keep it cool.My other engine has a true 15.3-1 CR, I should have ask this in the begining what is the best CR ratio to run?

Help me out everyone with some more good advice on the stroke,CR and camshaft choices. I want to get everything I can out of this build,with Horse-Power being #1 goal but do not want to go over the top and try and build a 9,000 RPM engine. I don't think 7200-7600 RPM would be to much.
This engine will be going in my dragster so it can handle all the HP a engine in this range can make and more.
