Good information. I have a srt4 caliper & installed BC stage 3 race cams & I ported the exhaust side gasket match. I will just smoth out the intake side. Has a bws turbo & all the other goods.... looking to make 430-450 wheel on e85 only.
Well i hand ported my heads. Left the intake side at 100 grit and mirror polished the exhaust side. Mostly grinded out casting flash ,knife edging and pocket port. Head got bigger cams, brass valve guides, +1mm ferrea valves. valves,gsc lifters. For an all-motor 6g72. Took about 15-20 hours to port those heads. I would call them a stage3 port job. but everyone "stages" heads differently lol. Its such an odd-ball build most tuners are like oh no no no we aint touching that. So left to tuning it myself also lol.
can i ask you? my 1000hp street car cam choice. 1000cc bike embarrassment use only rb29 (stroker) e85 manual 4” turbo back ex made 1000whp before on 41psi i decided too cnc port and now cam choice-either (purchase) 272 or 288/288 (already have these), OS valves all round. light valve-train power band from 5-10k😊 i listen too you and think maybe the 272’s aren’t using all the ports capabilities i ran the 288 before and frankly liked them
