fixitrod Posted November 18, 2003 Report Share Posted November 18, 2003 An aftermarket head is always a good idea. I don't use one yet, but I eventually may. They cool better and they are adjustable. You don't need a new gasket everytime you and to pull the top off to look inside either. They are suppose to be less likely to leak with higher compression also. It's not necessary and you can add a head at anytime. Quote Link to comment Share on other sites More sharing options...

dlnoss Posted November 18, 2003 Report Share Posted November 18, 2003 I don't know much about the Vitos SS pistons but if they don't raise compression and your aren't ported or advancing your timing, 21cc domes are what I would recommend for pump gas below about 700' and 20cc for above 700'.

. Posted November 18, 2003 Report Share Posted November 18, 2003 correct me if i'm wrong but the ss pistons do the same as raising the exhaust port which lowers compression? Quote Link to comment Share on other sites More sharing options...
Oilsmoke Posted November 19, 2003 Report Share Posted November 19, 2003 It maybe be wrong if the piston rings are in the same place. Compression would remain the same. if the exhaust side of vito's SS are dished as to let some more exhaust gas escape. Hmmm and as I type this I find myself not Sure. Hehehehe ANy thought's anybody.
