I'm thinking of having the P-1SC with an intercooler installed in a few weeks. I'm wondering what other things I should look to upgrade on the engine to prevent any trouble in the long run. The only thing, engine wise, I've done to the car is put in 355 gears and long tubs with a cat less H pipe. My brother has me paranoid that I'll blow the heads/caskets but the little reading I've done hasn't mentioned much of that or problems like that. Someone suggested upgrading the heads and cam at the same time. Anyone have experience with this and might offer some suggestions?
