Since the L81 is basically just an L 48 with a computer, there are tons of threads about heads cams, carbs etc... through searching. But an easy upgrade IMO is to go with Vortec heads, a matching cam and of course a vortec intake. The vortecs are better all the way around and can be found easily. As far as aftermarket I like AFR heads.

i think the vortec heads are over rated. the iron eagle heads work well, and require no machining for higher cam lift plus you can use the regular valve covers and intake. i think the center bolt covers look like crap too.
