Title: Not worth the hassle of installing.
Review: Product was a pain in the butt to install. I put this on a 4.9 Liter OHV cadillac motor. Had to cut & bend the brake booster tube just to get it to clear the egr valve then had the engine stuck at full throttle on startup. When I went to remove the spacer I discovered the threads pulled out of the block & were stuck on the steel mounting screws. On The plus side I did get to change out my leaky old tbi gasket! Thanks transdapt.
