Well the Ls6-1 isn't a "tree fitty" but close enough. But in this case a good set of ported factory cathedral heads 243/799's being the go to for most people will be your best bet. If you got a good porter local where you can save a little $$ I'd do that. But right now I think Texas Speed' porting service is still at Black Friday prices so it might be worth looking at to compare prices. If you wanted to go rectangle port you would need the small bore version. I know gm has a small bore version for fairly cheap but going that route you'll need a different intake also adding to the cost.
