Need Head Advice I am 99% sure of the cam I am getting. It is a 232/236 595/598 112LSA
I am looking at all the head choices. I have considered porting/polishing my stockers, finding LS6 heads porting/polishing those or just getting some aftermarket LS6 style heads. I was planning on 2.05 and 1.57 valves with patriot dual valve springs I am looking for suggestions. Anyone have experience enough to know if I will run into PTV clearance issues?

I have the same cam with -2cc pistons, .040 gaskets, 2.05/1.57 valves unsunk, and ~58cc 5.3L heads. PTV is within acceptable ranges.
If i were you I would notch the pistons when you have the heads off and get a set of heads with nice small chambers, that will bump up your compression a good bit, which will help with low end TQ and makes it nicer to drive on the street.
The dual springs will last a long time too with a cam that size.

I would suggest buying or selecting a cylinder head and then designing a camshaft approiate to the head CI manifold header exhuast combo. Seems a bit backwards to me to choose a camshaft then try to build the rest of the engine around it ?
