Wich heads for 550 hp ??
 

I'm looking for a set of heads that will give me about 500 550 hp on a 351. I'll be a race engine but i don't want something too costly. I don't want too much compression no more than 11:1 and I don't want to spin the motor part 6500. Any idea

If I were building a motor, I'd go with TFS High Ports.

Something ported, any of the aftermarket heads are good. TFS, etc.

Skyler

if your keeping it 351 cu. in. i would say trick flow twisted wedge (ported) if your stroking it i would say trick flow r series, with some intake and bowl work.

I like my Canfield's. They could handle 500 hp easy on a 351.
