Product Description
1G DSM Turbo 4G63 cyl head
C6 Casting which means this is a 1G 7 Bolt Head (Large Intake Port)
Features:
-Recently decked once, finish looks good
-Aftermarket SS Valves, brand unknown
-Aftermarket single spring valve spring, brand unknown
-Aftermarket Valve Spring Keepers, brand unknown
This looks like a good candidate for a mild street strip build with a mild cam and not too aggressive valve and spring upgrade.
As always, I highly recommend having the head gone through, replace the seals, check the deck etc.
