For sale is a pair of NIB Pace Performance Vortec ZZ5 cylinder heads. These complete assembled heads are a brand new iron Vortec casting with GMPP springs installed and clearanced for up to .550” of lift. They have steam-holes drilled for use on a 400 block but can be used on a 350 with no side effects. They have a dual bolt pattern for both Vortec and standard intakes (standard intakes must be machined to match head intake ports). They’ve also been drilled and tapped for 3/8” shoulderless screw-in rocker studs. I also have a set of roller-tip rockers and some Fel-Pro head gaskets that I will include for free. I’m asking $650 shipped for the pair. Also willing to trade for firearms and/or cash. Preferably, semi-auto rifles and or handguns. PM me with what you've got.
