Probably rite heads call them. Should check valve guide clearance. And remove paint from China wall.

Had machine shop go thru heads and check valves and all scrape off that paint. May cause leaks ? Thanks for the help

720 HP @6500RPM for a NA 502 I/O application is a schit ton. IE: More than a lot. :)

Do you have the sheets or curves? I would like to see what the TQ curve looks like.

The aeromotive pump and bypass regulator have served me very well. The cons are that it’s not cheap and there is a lot of plumbing involved by the time you include the in line filters and return lines.
