Cylinder Head replacement?

[Waterloo]

I would install a new OEM head... Been through the two in frames in two year bit, it ain't worth it. Just make sure you machine/cut the block and shim the liners and set the protrusions. You skip doing this, and YOU will be in framing it again in short order. And use lots of Permatex Ultra Slick on the bearings prior to reassembly. Also, very important, pre-lube the motor before starting. Good luck. ;-)
