Picked up a low miles lq4 today, so far just have the intake off. But I pulled a valve cover and man does it look clean, like brand new, theres marks from a paint marker on the inside of the valve cover, on all the springs, and the inside of the head, looks promising!

Will be running stock bottom end.
I want to use the 317s as I can get them milled for nothing, literally. My question is how much to mill these guys?
Stock for stock, they flow the same numbers as 243/799 castings, or so im told, but with bigger chambers. The 317s have 72cc chambers, where the 243/799s have 64cc chambers. Obviously I want to get them as close to 64 as possible, but thats just not happening. If I use the math that .007 milled is 1cc, then to get to 64cc id have to mill .050+, just not possible.
But if I mill to much im going to kill my valve clearance.
Trying to get this figured out asap, id like to get the heads to the shop tomorrow if I can.
ALSO, anyone have an used ls cam laying around, looking for bigger than TR224.
