Are you sure you want to use the standard head gasket? Also highly agree with the custom pistons advice definately the go. Also highly agree with the work on the bottom end advice as it is your base and sets the tune for the build, if you want a really nice build make sure the bottom end is sweet, maybe get it cryo'ed. Because if you have and awesome top end and a terrible block you will do damage because the block needs to take the abuse. Also the reason for the higher price of the stroker is the extra care, treatments and precision required eg whats the point of a stroker that drives like a truck and only puts down 200hp - 250hp.
