How do you have zero deck with a dome piston? In your orig post you said you dynoed at 350 HP at 5700 rpm.... Then you said you want to get to get 430 to 450 HP.. I don't know how your gonna gain almost a 100 HP over a already decent set of heads, unless you turn more RPM. Its a small displacement engine, its gonna be a high rever to get anywhere near 450 HP.. I think a custom grind solid cam is the best bang for the buck in this situation....

Dome top pistons have a compression height just like any other piston. They are essentially a flat top piston with a wedge shaped dome, only the dome part sticks out above the deck. the rest is 0.000" below the deck. hence it's a zero deck engine with a dome top.

It dynod 350hp at 5700 with stock heads.
With better flowing cylinder heads an engine makes more torque higher in the RPM range, often moving peak horsepower up several hundred RPM.

I was never expecting 430-450hp with the current camshaft and a head swap alone, but wanted opinions as to whether the gains (beyond 350hp) were worth it while leaving the cam and only changing the heads.

This engine is 323ci, it's only 5.2% less displacement than a std bore 340. With the right cam and heads it could make serious horsepower.
