Cobra gt40 head Question??

The 1.94- 1.90- 2.02 big valve works in an aftermarket piston, as FORD cuts their Notches for the 1.85/ 1.55 valve size!! It isnt the depth of the pocket.. it is the outside radius of the pocket!! We have had issues with a 1.90 Valve, SOOOoooo.... IF you go that big the piston will more than likely need notching , or at least the piston notch "layed Back" to fit the Valve size... Cool??

Just a thought!! Keep the stock valve size ( for P/V issues) and up grade them to the undercut stem stainless valves.. you will increase the low to mid lift as well as the top end!! The shrouding in the chambers and the cylinders will be less than the larger valves and you will fly when it is all pulled together with a good performance valve job !! Just a thought... some times "bigger isnt better" Cool??

Any good quality!! You dont need ass kick'n, high dollar 8000 rpm quality!! Just make sure you have the "undercut stems", the machine shop could suggest some.. for YOUR application, Mine are $180.00 and I will ship them to ya free.. just a thought.
