I think im gonna use the same cams. 272 step II's . They got 10.2mm of lift so i think you need to buy valve springs as well and also gotta machine the head to clear the cams. Oh yes and also setup the shims.
My mods were . Hi flow turbo running 17psi . Hybrid front mount .. Full exhaust. stock computer with afm cut and speed cut taken out . 12.7 @ 114mph on street tyres.
