Thanks Russ for answering my questions.  I wasn't aware that I'd also have to change the front counterweight if I went with the higher compression rotors.  Thanks for pointing that out.  I'll see how things clean up.  Both rotor housings had coolant inside the combustion chambers but I'm not sure why as the intake and exhaust (the heavy oem one) manifolds were on.  Oh well, most everything was in pretty good shape so I can't complain but I'll have to see how clean I can get the worst side housing.

Thanks,
Jeff
