well i've replaced stock mhg's on 3.3 chrysler motors a couple times and just watched one of our techs put a stock mhg on a 2.7.the way he (and I) prepped the mating surfaces is he just used a wire wheel on his pneumatic drill and removed most of the gunk, then used a roloc pad to ensure smoothness...he has done a couple dozen 2.7's like this and never had a problem including his brothers and son's intrepids that have more than 40k on the motors (2.7's are notorious for rodknocking)...
now this got me thinking because from what i understand in order to install a mhg on a 7m special machine work is required...now i swear i searched but gave up and i'm just asking why is this so?i dont care getting the machine work done i just want to know why?iron block makes a differance?just because the head design sucks?just wondering...
aslo, what the hell does RA mean?i swear i searched for like 10 mins....
