Default Which head( 241, 243, 035) for stock bottom end and 8-9 lb P1SC

Here is the deal guys. I have an 02 Z06 and just got a A&A P1SC kit. Right now my car has 59cc AFR's and a Cartek 2X cam. So the heads and cam have to come off for the blower. Typically the A&A kit on a stock Z06 with headers makes almost 600 rwhp by 6600 rpm. Now I don't know how long that will last with the factory pistons. I would like to build a dead nuts reliable FI Z06 without going to a forged motor for now. Boost will kept to 8-10lbs max and the car will driven in the heat of the summer to the cool of the fall. 10.5CR is pretty hi. So I was thinking would it be beneficial to maybe swap the 243(64.45CC) heads for maybe some 241 (66.67CC)heads to lower compression or maybe even the 035 (71.06CC)heads to lower the compression even more? This is just to have a more liveable FI combo to run on 94 octane fuel. Since the cam needs to come out maybe there could be better choice for FI cam that can make more power under the curve than the Z06 cam? Cam needs to have a smooth idle-i don't see the need for alope with FI. I know th ideal thing would be to get a forged shortblock but for now what should i do to build a reliable stock shortblock. Thanks in advance!

Get the LPE gt2-3 cam- 207/220 573/.580 118.5 CL. it will work great with your set up. I would go with the lager heads to lower yor compression a bit. you will also get a little bit of torque back down low.
