So should i change the cams or leave them.. P&P is an auto...and a new valve train that will bring the hp up to some nice numbers.....what about blueprinting and balanceing....i figure that would help me out somewhat.if i do work to the head should i have to change the bottem end or could i leave it ??

 

I would focus on the bottom end mainly. That is the weakest point for a forced induction setup. The head is really the last thing you need to worry about.

Look into some forged pistons and con rods.
