moneybags Posted May 29, 2007 Report Share Posted May 29, 2007 It depends on wether you want to run race gas or not.. If you run over 150psi you might need to start adding some race gas. Like a 50/50 blend of race gas and 92 octain. Most likely if you want to run pump gas (92octain) Go with 21cc or 20cc domes depending on elevation.

spt Posted May 30, 2007 Author Report Share Posted May 30, 2007 Depends on what fuel you wanna run and your elevation... RIPPEN pa elavation and like to keep running 92 octane pump gas. Is it really worth it for the money Quote Link to comment Share on other sites More sharing options...
MILO Posted June 8, 2007 Report Share Posted June 8, 2007 pa elavation and like to keep running 92 octane pump gas. Is it really worth it for the money 'pa elevation' is pretty vague. check out this site for more specific elevation. topozone do you know what kind of head your getting? pro design / noss / ? the noss head couldn't be any easier to install, looks great, works great, and yep, well worth the money. the owner is great to work with also. he's a member on this site and is easy to talk to and deal with any questions or problems. you can't go wrong with a noss head. figure out your elevation, and check out the noss machine web site for the application guide.

XxMeltIcexX Posted June 8, 2007 Report Share Posted June 8, 2007 Noss heads the way to go, find out what your elevation is, the site http://www.nossmachine.com has a chart that will give you a "ballpark" figure on your compression. More comp= more torque and more stress on your bottom end. With your mods id stick to pump, but thats just me - the guy who spends 115 bucks on 15 gallons of gas. :laugh: Eric Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted June 9, 2007 Report Share Posted June 9, 2007 I would run a 20cc dome, that will be ok for 92 octane. Depending on elevation it will get you anywhere from 155-169 psi compression most likely. Quote Link to comment Share on other sites More sharing options...

lowriderb Posted June 11, 2007 Report Share Posted June 11, 2007 (edited) another thing to consider would be to split your cases and have your crank trued and welded so it doesnt come apart that would be for reliability.. then you could run some 19cc domes and just be on the verge of having to mix a little race fuel, though i have ran more than 150 psi of static compression before on pump fuels the general rule of thumb is around 150 you want to start mixing if its detonating.. all the different heads do pretty much the same things.. the billet heads (cool head, noss, rk tek, ect..) advantage would be the interchangable domes.. if you dont have the funds to get a new one find a used shell with studs (if needed) and just get some domes and o-rings. polish it up and your good to go..

ClimbAnyHill Posted June 11, 2007 Report Share Posted June 11, 2007 I recently purschased a polished Noss with two dome sets & acorn nuts $145 shipped. Before that I ran into a Pro Design $100, head only. Both have interchangable domes with each other but Pro Design requires you change to longer cylinder studs. I'd rather Noss for that reason.. Both DLNoss & FAST give the BHQ discount the same Noss head & think it's $225 shipped for the head, seals & choice of dome size. Quote Link to comment Share on other sites More sharing options...

KaosBanshee44 Posted June 28, 2007 Report Share Posted June 28, 2007 I'll say that "some guy" told me that the noss heads are junk the only good thing you can do with them is change the domes out but he said mill the stock head down and stay away from the aluminum heads. But hey just putting it out there i'm not saying i agree with him. Quote Link to comment Share on other sites More sharing options...

My head is shaved now but i mainly want one just for the cooling advantage. Quote Link to comment Share on other sites More sharing options...
