tryin to break in new engine, ruff idle

I re-use the intake gaskets if they look good. Just don't toque the bolts too tight or the gasket can split. It gets weaker with age, why now I use fel-pro gaskets that end with a S, they have a steel core sandwich in between.

A few rockers might feel loose after the engine has not be run in awhile but right after it ran all rockers should be pretty firm, if not you will hear them and its not good, parts get beat up quickly--not so fast everything is ruin, just its not good to leave them loose.
