They will not bolt right up, you can find more details in the engine swap forum https://www.thirdgen.org/forums/engine-swap/
If you are refereeing to the 60-70's ? LT-1, i doubt they would be a good match.

From what I've understood about the LT-1 heads is that they're reverse cooled, no good for your 350.

from what i gather there are a lot of mods that have to be done in order to get GenII/LTx heads working on a GenI SBC, it's not worth it at all imho.
