330hp maybe more if you use better valve springs than the kit springs.

320-330 is what is typically seen. 350 absolutely not.

heheheh........sounds like a CHALLENGE !
If he puts his mind to it and those heads are properly freshened, he could get it through an M6.
Guppy's right; it will take better springs.

Get alittle bigger cam if you want 350. But I dont see you being too far off your goal.

Those Impy head gaskets will give you alittle boost over the typical hotcam build. They're near the top of my 'to do' list.

I will classify my heads as "cleaned up".

All casting marks have been removed and intake/exhaust have been smoothed over a bit. They are still stock heads.

So it should like 330 would be a more realistic goal then?

Not a huge issue(it is a hot cam after all) but I was curious what a fresh build is worth over something with a bunch of miles on it.
