Head Gasket Help
I am getting ready to order my head gaskets so I can put the engine back together then in the car. I don't know what bore diameter head gasket to get. Here are the specs on the engine:
402 LS2 with LS3 heads milled .036 for a 64cc chamber
-8cc dished pistons with valve reliefs
The head gasket I am looking at is:
Cometic 4.060 bore .036 compressed thickness
I am not sure how far the piston comes out of the bore, my dial indicator stand is MIA so I am having a new 1 shipped tomorrow. How important is knowing that to selecting the head gasket? I know it affects compression ratio. I have read a few different places that on LS2s the piston comes out of the bore .005" but I am not sure since I have Callies Compstar crank/rods and Wiseco pistons.
