Some other shots.

What are the affects of porting the 2 "holes" for lack of better terms on the intake side. More so rounding them out and making them smooth. Also I did some light clean up work in the transfer area where I could reach with a dremel and some on the exhaust side but not polished out yet. Looking to get the dremel extension to reach up higher and the 90* areas. Any good links to porting articles? I only want to clean things up like the cylinder should be since I will be on pump gas or maybe 100LL
