you must mean lt1 and no not without extensive welding/modding. LS1 are totaly different however and theres no way possible for them to go on a traditional sbc.

The lS1 was not avail. in he early 90's so you must be referring to the LT1 heads. And yes its possible, but (crap i just realised someone already said this...) you need to mod it.
