Hey guys, I am trying to properly set my stud mount rockers, can I do a compression test with the upper intake off?

sure, just make sure you take the coil wire off, you wouldn't want it to start up

cool, but will it be accurate compression with the upper intake off? I pull off the 12 volt feed for the coil and disable fuel.

Yes, it is just like wot maybe a little better. Remember that you dont really care what the total PSI is, just the evenness between cylinders. Dont forget to take all of the spark plugs out.
