Does anyone know the max valve lift on an Edelbrock 1115 (flat)head.
I've contacted Edelbrock but still awaiting a reply 4 days later.
Also has anyone flycut these heads for extra valve clearance and know how much material there is to play with?
Thanks

Hi Kev, you should have no head-to-valve issues with the any of Edelbrock's Flathead castings.
Having said that we do machine the valve pockets in their smaller chamber castings occasionally, not in the 1116's however, see the photos below. The shot with the ruler is an 1116 piece and is over .500" deep as CNC machined from the mfr. The second photo is a pair of Offenhauser, these had smaller chambers going in! The earlier heads also show the "fire-slots".
We also tend to "fire-slot" most builds we do, and we always check for proper spark plug thread depths before the heads get bolted on!
Thanks, Gary in N.Y.
P.S. Hi Ron, hope all is well by you guy's up that way!
