I have a 4.3L stroker with a .050 overbore. Looking to order some fel-pro head gaskets for it, do I need to specify this overbore when ordering, or will the fel-pro 9642 PT-1 be sufficient?

Ford used to make a gasket specifically for .030" overbores, but I've not come across anything for larger bores and the Ford one isn't available anymore anyway. The Felpro gasket bore is 3.91" so you should be ok with that even at .050" over.

What is the stock bore size? I'm probably just going to go with the Felpro perma-torque for this build.
