The Mustang I am working on is a 1983 GT It has a 5.0 with a Performer RPM Intake, A Holly 600, Headers and a Slightly hotter than stock Cam. Ihave found out the block is a D2OE which is a 72 out of a Torino or Fairlane, The heads are E6SE which are 86 , It has Flat top pistons in the engine and what little info I could find about this combo suggests that them heads on that block with flat top pistons will reduce the compression well below stock??? So I need to know if this info is correct and if it is what heads would be a good replacement???? Thanks

Well, since the '86 HO motor was the only one to come with true flattop pistons, I doubt you are really losing that much, if any compression. I hope the pistons that you do have have valve reliefs for that cam. The stock '86 pistons had no valve reliefs and make head/cam selection darn neer impossible with out notching them.

Yeah the pistons are .030 Sealed power with the Valve relief
