richard-b61 Posted October 4, 2016 Share Posted October 4, 2016 Was wondering if anyone could point me in the right direction to find a END673 (Non-Turbo) head gasket. Quote Link to comment https://www.bigmacktrucks.com/topic/47146-b61-head-gasket/ Share on other sites More sharing options...
Willie dog Posted October 4, 2016 Share Posted October 4, 2016 Olsonsgaskets. com has a large selection of gaskets for antique engines. They can even make gaskets if needed.

I second that and move the motion to be adjourned. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47146-b61-head-gasket/#findComment-347817 Share on other sites More sharing options...

richard-b61 Posted October 6, 2016 Author Share Posted October 6, 2016 They have some, but they need to know the head bolt pattern, and I would have to pull my valve covers.

39 Baby Mack Posted October 6, 2016 Share Posted October 6, 2016 There's basically two different heads for a 673. 18 stud or 20 stud. 18 stud heads have a single corner stud on the drivers side. 20 stud heads have double corner studs on the drivers side. All 5/8" studs. One other thing to watch out for, there were two different 18 stud heads. One had all 9/16" studs, the later ones had sixteen 9/16" studs with two 3/4" corner studs in the corners on the drivers side. I hope this helps, you should be able identify them without having to remove the valve covers.

richard-b61 Posted October 6, 2016 Author Share Posted October 6, 2016 Thanks for the info Ron, I had a friend blow the head gasket on his B model last year so I thought I would buy a spare for mine since parts are getting harder to find.

richard-b61 Posted October 14, 2016 Author Share Posted October 14, 2016 Still need to call Watts, they don't list any head gaskets on their B Model pages.

I know nothing about the e6 but from the pictures they appear to be the same as my 673 N/A gaskets.

Those descriptions mentioning E6 are wrong. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/47146-b61-head-gasket/#findComment-348797 Share on other sites More sharing options...
beatngu Posted October 15, 2016 Share Posted October 15, 2016 Excellent, that is great news. I can buy a set next week opposed to after Christmas. Quote Link to comment https://www.bigmacktrucks.com/topic/47146-b61-head-gasket/#findComment-348799 Share on other sites More sharing options...
