Magnum Heads

Wow great info already, thanks.

dgc333, your setup is very similar to what I am planning:
360 zero-decked, kb pistons, xe274, air gap intake

I was first thinking about using RPM heads but then started leaning towards some form of stock heads with some work done. Now I'm learning more about the magnum heads and might go that way. The fact that they are much cheaper is a major plus. I definately want to get in the 400-450 power range.

Have you dyno-ed your combo?

BJR, in what situations are the heads prone to cracking? When used for racing and such? This will be a 90% street car with some passes down the 1/4 mile for fun once in a while.
