I did have LS1 heads but gave them away,not sure they would have fitted. Still SBC though. They were 10.2 compression ratio.

I don think gen 1 interchange with gen 2 interchange with gen 3 heads without modifications.
Can be done, but not bolt on.

Seen some come up on eBay,
462624 Small Block Chevy Cylinder Heads | eBay (http://www.ebay.co.uk/itm/462624-Small-Block-Chevy-Cylinder-Heads-/281778973134?hash=item419b55e9ce)
May need a bit of work, possible no better than what you have.

or I'm sure Real Steal have some nice Edelbrock aluminium jobs that will give a nice performance increase and weight decrease

You might need different front springs with those due to the lower weight
