Nope Not a chance. Gotta notch those pistons. The only head that will fit the 86 without notching the pistions is the Trick Flow Twisted Wedge and that's not even a sure thing on every application. Nothing else will fit without notching those pistions

Nope don't think so. Even the factory 87+ heads require valve reliefs. Especially if you are running 1.7's
