Been talking to a forum guru about upgrades on my ZZ502 and would like to go with better AM heads.

Any idea what a set of used ZZ502 heads are worth? They have about 130 hours on them.

Thanks

try street roders those heads are only good for low &mid range torque

I have seen then go for about $1500.00 if there complete. They are the same as the Edelbrock RPM's and the will be pick up pretty quickly by the hot rodders.

I'm "on the fence", deciding between a bigger boat, and upping the power in our current Wellcraft 23 Nova.

If I decide to keep the Nova and go with engine upgrades, the heads will go complete with the SS valves, springs, & rockers. I plan to replace intake, cam, lifters, and push rods also. The engine runs perfectly so I'm sure the parts mentioned are all in good condition.

Is there a particular/good web site to list the heads on?

Thanks for the input.
