What could I expect to pay for the machine work to align hone a 302 block and make it .060 over. What else should be done while it's in the machine shop? Class rules prevent much metal removal beyond deburring and squaring. Same for heads, what does it cost for a 3-angle valve job? Again, no porting or polishing or chamber work. Thanks

Do you absolutely have to go 0.060 over? 0.030 would give thicker cylinder walls and better sealing. Better sealing means more hp.

also ford says not to go over .040 on the winsors. your just getting too thin after that. KB
And too thin means cylinder wall flex, blow-by and power loss.
