You've never had a big block, have you?

My $.02:

If the engine was built to run on 94 or better, you are going to need to lower the compression. If it were me, I would figure out what thickness headgaskets you have and get a set of gaskets that are a fair bit thicker to drop the compression a touch. Then swap in milder low-end oriented cam while you have the intake off and be done with it.
