Another update: thanks to you all, I've sourced a cam from a '78 super sport and 2 towers. Got em from Bill Benton.

Hey Guys, It's been a little while since my last update, but it turns out that the head is really curiously messed up on that bike. It appears that it was cracked and rewelded at one point. Really interesting , but I sourced a new cylinder head just last week.

My question for this post is regarding the cylinder head: It's out of a 1976 750F. It appears that it'll bolt up perfectly, but I'm concerned that I'll miss an added o-ring or something small that is gonna result in issues down the line. Thoughts?

might want to get the new head surfaced before install,post a pic of the two heads to confirm what they are.billp

I have a straightedge and feeler gauge to check flatness. If it's in spec I won't bother. Ill throw up a couple pics tonight or tomorrow

Use case sealer on the 6 rubber pucks and be sure to use 2 o-rings for the oil orifices and TWO MORE for the other 2 'holes' where 2 more might have gone but don't exist. If you take out the cam tower studs be sure to use sealer on the lower threads going into the head.

put the head on the barrels with no head gasket,and then see if you can see light between them,use a flashlight from behind if you have to,both heads I tried this with had bow in the centre,confirmed by the machine shop.billp
