Ok- I've got a Magnum FE 2.0 liter from Japan, 8 valve truck engine. I am rebuilding it. It was really dirty.

So far I got the bottom end rebuilt- just reused stock pistons but thoughly cleaned them and used new rings and bearings, cleaned the block- rehoned the cylinders and painted it black.

Now I got the head cleaned an resurfaced. It has a small corrosion spot next to one of the coolant holes on the sealing side of the head- and the spot did not go away with a resurface. The valves are kind of gummy still- and valve stem seal or valve guide condition is unknown. The head holds pressure and doesn't have any cracks.

So here is my question- what do do with the head. I was thinking about doing a 3 angle valve job- cleaning the valves, installing new stem seals, check the valve guides- replace as needed. To take care of the corrosion spot- I was thinking of grinding it out- tig weld it up- then mill the head again.

Second question- how far can I mill the head? I'm using a Delta Camshaft reground 272 cam- so firstly I'm concerned about piston to valve clearance. Increased compression ratio makes me happy- so that is not a concern for me. Anything else I should be looking out for?

Holla at me ya'll!
