I bought a used head a few months ago. Greg at GSC sent me a email saying he just bought a CNC and now offers "Head Work"
Excuse how dirty the head is and Greg did the best he could to clean it up. I went with GSC because ive had great luck with his cams and customer service
I know AMS runs his cams and i made the 1014whp on his S2. I cant wait to get some new #s on this bad boy. My other head i had really just was cleaned up some and had +1 valves in her. So this head with my new setup should make some record breaker power
Here is the low down on the head. Greg will have flow bench #s up real soon.
Head:
GSC XR EVO 8 Cylinder head
1mm over Stainless steel intake valves, 1mm over Inconel exhausts valves
Kigley racing springs with Titanium retainers shimmed for 105lbs@ Seat ,13.2mm Coil bind
Full CNC Valve Job providing unmatched flow and seal of valves
CNC Intake, Exhaust, and Combustion chamber porting, Hand Blended finish
Bronze valve guides
New OEM casting (usually)
Flow numbers TBA
Cams
GSC 6008S3H
Hydraulic Lifter, S3 camshafts:
280 Intake 11.50mm 218@1mm 108CL
280 Exhaust 11.5mm 218@1mm 116CL

Why hasnt the head been skimmed as from all the pictures of its face that head has had a substantial amount of dett on it.

If you have had valve giudes put in then the head should have been heated to help this so you would need to skim it to make sure its flat,
Also the metal type head gaskets these engines use need a perfect face of the block and head for the gasket to seal to its opitman,
That amount of dettantion the head has seen also it would be strongly recomended to skim also.

If I was trying to make 1015hp I think I may want to go with a cleaner core.
Very nice quality work but I would be a bit shy about putting that on my motor.
