I know all about the conservative approach. I’ve been there more than once. Head gasket bad? Might as well do a valve job. Might as well do both heads. Hey why not new lifters? And those roller rockers are pretty cool. If I’m doing all that, why not a Stage 1 cam, and double roller chain? Etc., etc. I’m trying to do the minimum to get it running again and avoid the might-as-well snowball. It got me thinking that in most cases both heads are pulled for a valve job or whatever and thus the intake comes off without question. It struck if its really required if only one head has to come off. Sometimes things that have always been done a certain way just never get questioned.
The bolts are torque-to-yield so will have to be replaced. And valve guide seals are pretty easy.
