Lew91 Posted February 28, 2013 Share Posted February 28, 2013 So I decided to have a crack at it and I'm not 100% sure if I'm doing it right. Before After Is that enough or to much? I'm just going for a smooth look with no rough casting marks left in. Quote Link to post Share on other sites
shorty Posted February 28, 2013 Share Posted February 28, 2013 (edited) No where near to be fair bud and is best left to the very experienced or a specialist tbh, as the chambers should be balenced to give even flow. to give you an ideaExhuast (not a great pic but gives an idea)Inlet Edited February 28, 2013 by shorty Quote Link to post Share on other sites
shorty Posted February 28, 2013 Share Posted February 28, 2013 Sorry just noticed you said your going for no cast marks and mild smooth, in which case the port should feel nice and smooth with no lumps or rough burs left, so id say yours is almost there realy Quote Link to post Share on other sites
Lew91 Posted February 28, 2013 Author Share Posted February 28, 2013 Your inlet side looks massive compared to mine lol. That's alright then looks like I'm not entirely wasting my time Quote Link to post Share on other sites
shorty Posted February 28, 2013 Share Posted February 28, 2013 Lol yea my head is maxed out realy, I've alot of supporting mods to run with such a maxed head though. Quote Link to post Share on other sites
Lew91 Posted February 28, 2013 Author Share Posted February 28, 2013 Yeah I'd expect you need them really. Are you running uprated valve springs to? I've been looking for some but can't find them. Been looking in to high lift cams as well but they seem a lot of work. Quote Link to post Share on other sites
AdamB Posted February 28, 2013 Share Posted February 28, 2013 What tooling are you using? I wouldn't advise the intake side is smoothed, this causes the fuel to drop out of the air as there is no swirl effect which helps atomize the fuel droplets. Get something like a 140 grit flap wheel in the port once you have finished removing material, this will give a rough surface to help create a swirl effect to ensure you don't lose power. I would also recommend at looking at the intake manifold to do a little work on. Quote Link to post Share on other sites
Lew91 Posted February 28, 2013 Author Share Posted February 28, 2013 I was planning on getting a zisco or race tech mani any way, the standard ones dog ugly. I'm using a flapper bar in a air gun, it's like a flap wheel but with a polishers twist lol. I'm using 100 grit paper to rip it out and smooth it in, it's constantly rotating so will always leave a swirled rough surface. Quote Link to post Share on other sites
shorty Posted February 28, 2013 Share Posted February 28, 2013 Yes bud i am, i have cruise valve springs, 265 billet cams and a custom intake the same as the wepr demo car uses. My head was all done profesionaly by a head speacialist. Quote Link to post Share on other sites
