I'm in the middle of a purchase of a 360 block and i have the part numbers from the block and heads but i can't find a lot of info on these. Any help would be appreciated.

the heads are 4027538-360

Check here...

The block should be a 1976-1988 360. That head number (4027538) must be a part number rather than a casting number. 1975-1988 360 castings were 3671587, 3769974, 4027596, 4071051 and 4323345. Head casting number may be either on top over the intake runner or underneath under the exhaust runner.
