Hey guys,

Ive searched but havent found an answer. Has anyone sucessfuly port & polished their heads on a 3.1 v6? If yes was it worth the effort? Reason im asking is i found a pair of heads on ebay for 50 bucks, thought while the camaro is in the garage for the winter i could buy those heads and if i screw them up, im only out of $50.

 

go to this site

type in: port and polish 3.1

there will be tons of information on doing this.

 

no actually nothing there says if it has been completed

 

ben do a search for my user name in the v6 section, i posted pics a month or so ago of a set of iron heads i ported and sold.

 

 

i ported and polished mine a few years ago

 

ok, so im kinda new to cars in gereneral(i know a lot about mechanics, but not to much about doing upgrade stuff) but what does porting and polishing hte heads do. im looking to try and squeeze every bit of power out of my 2.8

thanks

 

Its just what it sounds like. You port the ports to allow more air to reach the combustion chamber and to allow the exhaust to exit faster. Then polishing them is smoothing out the ports to there is little to no resistance.

 

a little more defined on polishing: you can polish the exhaust ports to look like mirrors and it will help flow. The intake side, you don't really polish much, you want to leave it a little rough to help the air and fuel mix. theory says that polishing an intake port too much can hurt performance because of the air and fuel not mixing as well.
