Quick question about which head gasket to get. I have a 5.3 LM7 with stock heads and a tsp 220 cam, (.581 lift int and exh). I had the heads freshened up at the machine shop and had them mill .035 off. What thickness head gasket should I get? I know stock is .051 would I have clearance issues going to a .041?

 

Nope, I have built a setup with .040 milled stock gaskets and 226/226 .585/.585, no probs at all. You should be fine.
