Pro Maxx heads

[STREETREBEL]

Just got the heads back from the machine shop.
Everything check out perfect. Spring pressure right on. Valves seats sealed perfect. Valve guides good. Bolt holes good. Head surface flat.
FYI.

Big or small block?
What version?

My small block shocker heads were very good when I checked them out. Really good work was done by them. I later upgraded my cam and did my own spring seat mod. EZ enough. I installed Comp Hyd. roller springs with more pressure. .538 lift.
