if you're only going to run 9psi you can boost first...my stock internaled single-cam non-vtec just hit the 5 year mark running 9-11psi. if you're going to spend the time opening up the motor go rods, pistons, headstuds. nix the cams, springs/ret, and cam gears until later when you do some head work and really up the boost.

tuning should def be in any budget you do.
