what would be a good choice for heads and cam ... for a 6.2 l92 engine also the 6.2 is going to have forced induction by a procharger...should i just port the l92 heads and what should i do to them if i do?

 

Port the L92 heads, get a nice good supporting cam for the F/I and hold on.
If your keeping the long block stock... I suggest a piston upgrade in the future bare minimum. I have heard some stories of these new motors kicking in piston skirts. Or just keep everything pretty easy on the boost and power levels and see how long the factory short block holds on.

Either way, it's gonna be wicked. Just with 6-7psi and prochargers on stock trucks we have been getting 50-55% power gain. Adding a cam, and ported heads your gonna be well over 600HP with yours.

Can't wait to hear the results!
