the difference in years is more aggressive cams for the 92-93 integra

btw 94+ are 142 hp w/ a different I/M but pretty much has the same build up as the 92-93 platform and yes different engine code(B18B)....

Now would be a good time to do alittle work on the head before you put it on.. Maybe a port and polish, valve work, and upgrade to the 94+ intake manifold.

 

it will be minimal, but the ports have slightly cleaner casting in most cases.. as time goes by, any good manufacturer improves their processes. the head might have less mileage, might have slight changes in valve angle or certain material composition such as guides or rocker pads, etc. im not sure on the camshaft.. perhaps its updated a little over the b18a1 but thats only a guess. if you have to change for some reason, do it. if not, i dont think it will be worth the expense of a new headgasket.

 

wow, 2 posts up before i even finished typing..

 

thanks for the info from what u guys said so far think im gonna just hang on to it for now look for the intake from a 94 + send head to the shop maybe by summer put it on after i get my current setup to the track , see what the difference is eventually i would like to go ls/vtec , just lack of funds right now thanks again ( not totally postive yet just what im thinking right now )
