Question Small block head# 3884520

I have been trying to locate a block number on my 1967 327 motor. I have looked in every nook and crack readily available.

I was able to pull the head part #'s 3884520 (H256 RT head & H186 LT head). They are valved 1.72 / 1.5 & 60.530 CC's. I suspect the motor is a small horse power 327 based on this info!.

By chance can any one tell me something about these heads and what HP 327 they might be attached to.
