J head porting

Well I think this is about done!! I’m running a 6 pack intake so if I can get these to go near 240cfm at 500/550 lift with a 2.02 valve I’ll be happy. Now to start the other 7 cyl.

Looks nicer than the porting I did on my 675 heads lol. That guide tail sure does take a long time to grind and shape.

Very nice.
