Can anyone help me identify some more info on my 350 Block and Heads?

Heads 3795896 Date Codes L174 and L164 T with a triangle. I believe these were made for a 283 V8, previous owner stated that they were 327. corvette heads.
_______/\_______
Symbol on the end of the head |_______________|

The block GM57LG SGI casting 14093638 on the side of the block 638.

Block appears to be 87-93 350 with roller lifters
