Upgrading a stock LS1..bang for buck

[DRJDVM's '69]

Well it looks like my low mileage 98 Camaro SS with a pretty stock LS1 may have eaten a bearing... the car sits for months, and the theory is that the oil just broke down, combined with some possible dry starts from sitting just ate the bearing surface....just started the pull out today, so the motor isnt broken down yet.

So I figured if I need to pull the motor apart, its an ideal time to update/upgrade some stuff.....dont want to go crazy.... the car doesnt see much action, so I dont want to dump a ton of $$ into it....

So I'm looking for some low buck upgrades..maybe basic ported LS3 heads, lifters etc, better cam.... any basic upgrades from any other other LSX platiforms that would be a decent bang for the buck?

Maybe just port the stock LS1 heads and cam?
