IT rules allow the ports to be cleaned up 1" in from the gasket surface. Nothing else in the head should be touched.

The ITCS shows that car to be eligible as a "87-89" year, so there IS NO later GTI from which legal cams could be sourced. If they are out of the 2.0 (the '91-92 model), they are NOT OK.

PS - If you buy it, you'll want to ditch the illegal rear spoiler, too.
