razorback11 Posted November 12, 2015 Share Posted November 12, 2015 Rebuilding a 65 B-61 and thought that I would change out the head gaskets on the END 711 (non-turbo) while I had everything torn apart. Machine shop tells me both heads are cracked. I live in Yorktown, VA. and I can not find a shop nearby that welds cast iron heads. Thought someone here at Big Mack Trucks may know of a shop that I could bring these heads to so I can get them get welded up. I don't mind traveling up and down the east coast....I just don't want to drive all the way to California to get them fixed. I would be interested in purchasing a set from someone who can spare them (as long as they are not cracked as well). Any help would be greatly appreciated. By the way, I have one piston that looks as though it ate its rings and the top is scored badly. May have to find a piston as well. Would appreciate anyone with a spare piston to respond and maybe we can make a deal. Thanks fellas and ladies.

64C85 Posted November 12, 2015 Share Posted November 12, 2015 I believe I have one or 2 heads (need to check) and know for sure I have 4 pistons and some other 711 parts. I'm located in Williamsport, Md 21795. PM me if and we can take it from there.

j hancock Posted November 13, 2015 Share Posted November 13, 2015 New style 711 engines have all head bolts the same size 5/8" and old style 711 heads have 3/4" corner bolts with the remainder being 5/8". The bore of a 711 (707 CID) is 5" and 673 (672 CID) is 4 7/8". 2 Quote JimIt doesn't cost anything to pay attention.

B61FD15 Posted November 15, 2015 Share Posted November 15, 2015 Please do, rebuilding a single axle B61, same year. Runs great, but going to have to re-seal everything next year. So it will be nice to know who to contact about things if I have issues.Sent from my SAMSUNG-SM-N920A using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/42630-my-end-711-heads-are-cracked/#findComment-311451 Share on other sites More sharing options...
