Im not sure if this has been covered or not but Im looking for a 3-layer metal head gasket for my 7M-GTE but Im not sure what thickness to get. I tried looking for the stock gasket thickness but I cant find it. I know the thicker the gasket the lower the compression. I plan to run 15 psi on the stock CT-26Any imput would be great. Also how much boost can I push safely with the stock internals on the ct-26?
