You are very limited to what you can do on an L27.
You can by Yella Terra 1.8 Ratio Roller rockers from ZZP for a 94-95 L27 5/16" studs for $350. You having a 92 (which I just noticed), which means you probably have 3/8" studs, so you'd have to have the cylinder heads removed and have them machined at a shop ($160 more). This would net you maybe 10-15hp.
Aside from that, you can get a fenderwell intake, a more open exahust, and that'* about it if you don't want to go custom.
As I mentioned, I've spent the last 6 years trying to make my L27 faster, and I've been unsuccessful for the most part. All of my work has been custom, from shortening the intake runners in the upper intake plenum insert, to porting the LIM, and now recently I've taken on the task of porting my heads, which there is a LOT to gain from. Its actually fairly straightforward if you have a steady hand and a dremel, which is all I'm using at this point.
Sorry to break it to you, but if you're not willing to learn how to port your intake manifold and heads, you won't be getting any more power out of this engine. I dropped $300 into my roller rockers and I've been trying to figure out this whole time why my mods aren't making that big of a difference, and while porting these heads, I can finally see why.
