View Full Version : cylinder head replacement

04-12-2016, 12:25 PM
Ran into some issues with my cylinder head, a few stripped threads (including a plug thread) and a bolt snapped in the old head...so I got a same year replacement cylinder head (1973) and a top end gasket kit.

I finally received the "new" head in the mail and its in pretty good shape but I this is my first time getting into the internals of this engine (or any engine for that matter) so i want to make sure i do this right.

It looks like it needs some cleaning, but I'm just looking for general tips or procedures someone more experienced would go through if they were in my position. The steps im about to take: take my old cylinder head apart, then off, clean the parts im going to reuse (rocker assembly, nuts and bolts as long as they are in good condition), after preparing the "new" head, put it on and reassemble (+gaskets). 687256872668727

It appears that one of the rockers that controls the exhaust flow is stuck slightly (as seen in the picture above) and im not sure if thats an issue and if it is, if its one that i can fix through cleaning.

I would appreciate any advice anyone can give me on the matter, thanks!

Get the timing right the first time........ And make sure you bought a good manual before you start.........

Is the cam still in the head??? You didn't show that side.... If it isn't??? Sure the valve being stuck open isn't a good thing..... I would say the new head will need a valve job.... What was wrong with the one that was on your bike????
