patriot heads, any good? im actually contemplating buying a couple sets of bare heads from them. the 320's and the 360's for a bbc. my next question is which set would u put on a blown 520ci alcohol motor 25lbs of boost, motor 85% of the time drag racing it. i spin it usually about 7500 to 8k religiously. in my opinion i think i would be at the end of the scale for the 320's because of what im doing and my cubic inches of the motor. that being said, would the 360's be to big? i need the motors hp range to pull from 5 to 8k rpm's.
