I have a slant head motor and from looking at the picture, I don't think it would really clear much better because there is basically no room there. Because it's at an angle though, you might be able to remove it without pulling the motor. It's hard to tell from just looking at the picture.

Will a slant head work with the motor? I have no clue.

I just finished refurbishing a couple of those oldies for some kids in the family. They are the envy of the neighborhood now!!! How cool is that?!? The classics never go out of style... As far as slant head idunno, but if it does work its seems you may beable to change plug by loosening the mounts and 'shifting' the engine a bit to remove plug. Easier than pulling the whole thing...

found cure replaced studs from engine mount with hardened hex head machine bolts i can remove the rear and take out alum spacer and loosen the bottom and move engine just enough to get the plug out . tried it on a spare frame white im waiting for paint to dry. i love these bikes to death. also i think i have enough room to put a sick bike parts shifter kit on and im gonna use the top tube mount suicide shifter for the 5 speed. if pedal sprocket's will clear engine ill have to measure.

You could rotate the engine a little on it's mount, bring it down a bit in front to give you clearance around the plug. Removing the spacer block on the back mount gives you a lot more space to work because you can slide the engine back to wrap around the frame. You might have to fabricate a new manifold for the carb to get it level and in the right place, but that is a very simple cheap welding job.

oops, I reread your post it sounds like that is exactly what you have done. cheers.

One of the ones I just finished is a 90% original 1967 Fair lady stingray- stock 'Brilliant Blue' my niece is in love with it. Makes me happy to see her so happy. Sorry, not trying to hijack yer thread dude, back over to the head question...
