Ok, I am very new to FI and have been trying to read a lot before I post. Currently my car is a stock block w/ TEA 5.3 heads milled to 62cc and an EPS 226/230 cam on a 112 LSA. Per Pat G this setup is around a 10.93 CR.

I am interested in a Procharger but realize my CR is too high. Could I run some dished pistons to bring it down, or would I better off with a new set of heads?

Run E85 and you won't have to worry about the compression.

Stock Ls2's have about the same c/r as you. LOTS of them living large with centi blowers. Your cam isn't a text book "blower" cam, but if you like the manners, it will work fine. You can always swap to a set of 317 heads to lower the c/r if it bothers you too much.

^^^I was going to say the same thing. you should be good but you will be a bit limited on how much boost you can run.(but your limited anyways on a stock bottom end.) or you could also sell your heads and use that money towards the blower and a set of 317s.

with a set of 317s you should be fine with 8-10psi of boost.

With your current combination I don't see you having any problems running 8 psi of boost. You could add methanol injection for added protection. Bob
