I did make an approximate sixty degree face angle exhaust valve using my vertical lathe, aka, drill press😎 While it does contact the wide exhaust seat, and would probably narrow the 45* part, it would take forever as a valve grinder rather than an actual cutter, so I scrapped that idea. I reassembled the heads this morning after a little spritz of black paint. Of course they look just like when I started from this angle. Retirement party to go too but maybe heads get installed tomorrow

Want more power ? 1989-1992 Allante 4.5 V8. 91-92 is easiest, get tranny also.

Agree some places are easy, others not so. Photos would help

All I can tell you is that after I ported and polished my heads, intake manifold, supercharger, and exhaust manifolds, I felt an increase in acceleration and torque. But until I increased the size of my exhaust, (1/8" to 2 1/2") I felt the real increase in power. It will now light up the front tires from a stop.

Where are the areas of rust?

Stuff like that never goes bad. Who knows, maybe could be used for artistic talent you don't even know about yet.
