Re: ZL1 heads
C port heads from the 80's. Had a set on a blown L88. These are Engine Prototype Developement heads, Larry Olsen. The top Pro Stock cylinder head shop in the country during the eighties. The was a time in Pro Stock that more qualifier's had EPD heads than not, at any given National event. Never had any reliability issues with mine. Port work cost WAY more than what your asking for the heads.
