I am gonna be installing a new cam here shortly hopefully. I will also be installing new mopar performance roller lifters, valve springs, retainers, keepers, and seals. I was wandering since I will have all of this stuff apart would it be a good idea to go ahead and pull the heads to replace the head gaskets and also to port and polish the heads? I have a exhasut manifold bolt broke on the driver side head so I think that I will for sure pull that one to get that bolt out. I tryed getting it out when I installed my header but no luck. Also what exzactly is port and polish? Is that something that I can do myself or do I need to bring the heads somewhere? I would also like to do my intake manifold. Anything else that I should do while I am there and replace?? I already have the 1.7 RR's.
