I have a ported high torque cylinder with a high torque piston (L-ring), but it has blowby issues, it's a #22 (not the elusive magnum #22 though). I also have a reg'lar high torque cylinder, with no piston. It needs a hone, but other than that, it's ready to go, no porting. Oh wait, it does have a little intake matching action going on. Anyway, that's what I got. Email if your'e interested; if not, I understand.
