Yeah the heads look like they were done right, with the exeption of breaking through to the valve cover bolt, but who knows it may have been done on purpose to open up as big as posible, doubt it would cause any issues.

I'm gonna try and locat a replacement piston and see what its got. I'm also gonna try to determine the lift and duration of the cam and see if something else might work better, seems like its screaming for a solid lift cam!!!!!

I'd be content if I could get away with just running a gallon or 2 of race fuel mixed in a tank, but if its too much more than that, I may have to rethink things as that could get pricy for a mainly street car.
