i run a 20/22 for a long time, had my truck sailing down the interstate at over 100, turning 6000 rpm in 4th gear when i dropped a exhaust valve, and thats the block i have in it now, EXTREMELY TOUGH MOTORS
You got that right! You can't imagine the pure hell my 81 block has gone through, temp gauge pegged for long periods more times than I can count, but it still runs fine. Maybe it's time for you to do a writeup on the building of a hybrid. It'd be nice to have a sticky on it so we could reference it for knowing how to do the valves, etc. I have mine apart right now, so if I'm gonna slap bigger valves in now would be a good time, and knowing how to fit the 22r valves in would be great.
