RE: Ported Heads

I havent down loaded those yet. Sorry coming soon! The work that was done to the Ex.port was blended throat to the seat 2angle valve job along with valve guide rework do to to tight tollerance from factoryand exhaust valve wastrying to stick. I had evil thoughts of going with a 7mm valve stem with 50 degree seat angle for supper high flow. I still picked up 10 to 15 cfm good for mid to top power picked up5 to 10 hp anyway! I also had to becareful with the exh.port do to the fact that the compression release bleeds off in the port so I blended exhaust port to diameter of exhaust gasket with the same contour of port.
