Figures I get the top end kit and the dowel pins for the cam were not included but instructions with cam say they are. I took the cam to the local performance shop and got that taken care of. I put the cam in and next it was time to do the rolloer rockers after the head install. when I was rotating the crank to do the next set of rockers i hear a sound. Well, well, well. what do you know. one of the keepers popped off the vale spring retainer. I cant find it. must have shot across the garage somewhere.Great now I gotta wait till summit sends me a new set of keepers. ALso i need to buy a new head gasket since i removed the head. I was planning on having fun and drinking beer gettin my engine setup. Thanks alot for a quality product trick flow. Its a good thing this didnt happen after i put the engine in the car and fired it up huh. Not one screw up but 2. What if this was a daily driver. Good thing my stang is a garage queen.
