I am convinced the 20r is better than the 22r as far as drivability goes. Much more rev happy and feels like a better torque curve all around. I'm sure it's the head design.
I looked in my dyno library, I found some 20R engines I tested back in 2001. I will verify data and specs, do some pulls, and try to post something tomorrow. I have some pulls with a 20R stock, a 20R with Weber, and some cam changes.
Then we can put a 20R head on a 22R block and pull it's torky little butt about 5 times and see what pops out!
Gnarls.
