911 race cams and head recess
I am in the process of rebuilding a 2.0 911 race engine but I cannot find any info on the cam timing.
Casting number 901 105 134 0R
Stamped on back 594 595
Etched on back "Full Race"
Stamped on front 03
Inlet valve lift @ 0.004" clearance 12.54mm ( 0.494")
A previous builder has machined a lot from the head faces where the gasket touches but hasn`t machined the recess at all.Instead he`s machined the top of the barrels.I`m replacing all barrels and pistons and need to know what the dimension is for the head recess.
Can anyone help please?
Thank you
