Hope these questions aren't too stupid

I am wondering whether or not I need to get my pistons decked as I have had the head skimmed(can measure thickness if req'd) and I am a bit unsure of how this will affect the compression ratio, I have a st2 conversion which was fine till head gasket went pop (found minute fracture in block so brand new 200 block was bought).

I am also unsure as to which head gasket to get, I have heard bad reports from tuners re-cometics and some advise gp A and some say to use Multi layer to sort compression.
Also told to use oe stretch bolts instead of arp's!

Any advice or help will be greatly appreciated

you will have to get the head measured as it will effect c/r there is a minimum height, you could use 4x4 pistons to reduce c/r and reduce the cold start up noise of a 2wd engine. i have just rebuilt mine and used the arp kit and a group A head gasket. any other questions 01633601148 leave a number if i am not around, drove off with my mobile on the roof a few days ago. regards ED
