If that's the k star stocko shocko 44 mm kit I suggest you look at it pretty carefully. Quality is sketch. Check to make sure the transfers are open at bdc and you will need to deck the top to get a decent squish and mine wasn't square. Go get a dr and bolt it on instead. Upjet that baby to at least an 88 main and break it in with a temp,gauge. I finally got mine right on the third piston.
