hey guys, just purchased a set of used 6049 x aluminum heads with a stage 3 port job done on them , and i was wondering what type of head bolts i need for them. do you have to run the shoulder type head bolts or does it require the washers like some of the edelbrock heads use or would just a simple arp bolt work ?. also - these heads didnt come with spark plugs - anybody make a suggestion on what they use ?. this combo will be na with about 10.5 cr with an 8cc dome piston. whats the deal with "mls" head gaskets i keep seeing, are they supposed to be the latest and greatest or ??? im gonna run these on a 69 302 block, so keep that in mind for any answers i might get. thanks !! :)
