ZZ4 Heads

For sale are a set of ZZ4 Cylinder heads (Casting Number 10088113) that I purchased from a man who ran them for 500 miles on his ZZ4 350, and I have ran them for another 300 miles. So these heads have a total of 800 miles on them. The heads come with the same springs GM sells to supplement the Hotcam, they are capable of .525 lift. The heads are un-molested and will drop 50 lbs off the nose of the car.

58cc combustion chambers
1.94 1.50 valves
D-Port Exhaust
Angled Spark Plugs

This is a startup video with the heads

These heads sell for $619 a piece on Summit and I am looking for $600 for the pair.

Contact me if interested

Re: ZZ4 Heads

Yes! That is what I am running on my 350 TPI right now. You just need to open the center two bolt holes on your base on each side and it will bolt up.
