head bolt bulge in runner?

Marland,
The next step would be gasket matching and bowl blending, then chambers mods. This is with the cam that your using, a larger cam will make more but the heads have to be done to handle the extra lift and duration. Also too that the lighter the weight of componets and the better machine work will increase HP and roller cams and valvetrains can increase HP up to 30% more than the flow of the heads.
Your heads make 364 HP from the engine, the 322 engine makes 430 HP from the engine and 344 HP to the tires with a small cam and intake, from the flow #'s on the heads. Now due to the light weight parts the engine is really making near 400 HP to the tires and 500 out of the engine, in a detuned state, as we netted 354 HP to the ground on the first day.
