Your 460 is a little different than most 88 460s. Ford introduced EFI in 88 for most of their 460s. Your engine is a carry over with a carburetor. Use an intake manifold gasket for a 87 with valley pan. The carbed 460s have an exhaust passage through the intake manifold. The EFI 460s does not.

A leak down test would be more effective than a compression test for finding a head gasket coolant leak.
