Can't decide on heads. . opinions??

475-500hp, you don't need airwolf or anything fancy.

Too bad ede support doesn't have a clue about what their heads will do. A decent port job on them will go 280cfm which is plenty. When you really start to work them they get into the 300ish range. BTW, what they flow at 700 is worthless if you're lifting the valve .500ish. :)

I don't know anybody else that got close to the claimed #'s out of the airwolf heads on their benches.

You'll need a pretty raspy cam if you want 475+ out of a stock stroke 340 engine. Not going to make it with a xe268H...

I wouldn't buy anything from Dr. J's after his screw job on a friend of mine.

Pick your parts, pay your money.
