I am going to be rebuilding my 800R in the summer and was wondering if anyone has ported or polished the blocks on this themselves. I have done several Chev. small block heads and was wondering if anyone could give info or diagrams on porting for my 800R. I ride in the mountains at 6000'. Do you gasket match or port for the Y pipe as well. Any info would be appreciated. Thanks.
