i have a 95 gt 5.0. my rings were bad so i bought a 302 block with heads,intake,holley carb for 200 dollars. i was planning on swaping all my stuff from my engine to the 302 block and be good. but come to find out the block is e6se, with flat top pistons. i know about the piston /valve clearance issues. should i risk it trying the e7 heads on the e6se block? or put the e6se heads back on and rebuild the 95 f1se block how i want?
