cylinder head removal

Post by kawonda750 »

Hi. I am in Ontario Canada and working on my 3rd GT750. This is my latest winter project to keep me busy when I retire in a couple weeks. I have all the head bolts out but the head will not budge. Is there a hidden bolt or one from underneath ? This is a 76 GT750 A that has been sitting for quite a long while but in very nice original shape. I have tried the rubber hammer and even prying it with no decent result. Thanks

Dave

Thanks for the pics. It seems that the stud in the centre 3 vertical rows from the left is too big. I assume it was put in after. It is too big and the head will not slide over it. I think that I will have to drill it out.

10 mm studs shouldn't be through the head!

If you look at the pic of the head sent by Cliff, the small hole to the left of the plug hole on the right had a nut on a stud. This will not go through the hole as I try to lift off the head. I am able to move the head slightly back and forth and the stud actually turns with it..
