Click on my NLMGG link in my sig and read a bunch of BS for a few days.
Basically, shave the head some(.030" minimum), put a thin headgasket on(.036" maximum), put in the K or H cam(or something with over 12mm of lift and 280? duration) and peak hp will have to be around 6,000 rpm which will require a properly sized header. LH2.2 can probably do it with the fuel pressure raised, but the fun will still stop at 6200rpm or whatever the rev limit is. It's much more fun to go to 7000 than 6200 in my car... The B21F intake manifold will help as well, the B230 one sucks for power.
Right now my car has too small of a header and the B230 intake on it that are choking things up top. That's why you aren't seeing more than 139whp on any of my old dyno sheets.
