Valve job numbers Hi all just after some info from people who have had valve jobs done on 799/243 heads. Firstly was it 3 or 5 angle? What where the numbers after the machining was done? And the gains you made? Thanks.

Sir nobody that makes power is going to give you angles on cutters sir. The time spent between bench and VGS machine could be days tweaking a valve job for a given set of heads. This is the difference between a $100 valve job and a $500 valve job on a set of heads. The gain of 20 CFM in valve job is 41HP. A $100 valve job won't do that.
