e7 Heads on a 1986 block, KB pistons. ???

[nidyanazo]

How much clearance will I have if I bolt up some e7's to my 1986 block? I'm rebuilding it and have hyper KB pistons with 2 valve relief's (sp?) Will I need to do anything else? Or is it a direct fit?

They'll work just fine. The problem with the OEM '86 engine was that there were no reliefs in the pistons, but the KB's have them.

I had the exact setup on my 91 block.......worked fine no problems with E7's and an E303 cam. No dish work required.
