I have often thought, ''what is too much port''? So I dragged out a set of rusty 906's destined for the scrap bin and started to 'port in anger'! Obviously I had some valves in mind for the ultimate porting jobbie. 2.225 intake and 1.880 exhausts. I went this way after having a long conversation with Robert Landy and 'what his DAD DID'! He said its all about the undershelf in the exhaust port which is easiest to remove with the 1.880, (all iron B/B heads) If its good enough for the Landy's, them I'm all in... Right back to the 90% RULE, mainly for intakes??? Folks are saying if the 'bowl area is more than 90% of the seat area', you is making a good head BAD!!! Last edited by Gtxxjon; 12/02/21 11:44 AM. Carpe diem, quam minimum credula postero, thanx Horace! There’s no point trying to fix stuff that ain’t broke,,, 'but if ain’t broke',,, you is not trying hard enough...
