I put it on TDC and both valves on number one are shut and the rocker will slide back-and-forth Stock rocker arms Huges pump up lifters with adjustable pushrods Whiplash Cam
Then you SHOULD have turned the engine over 1 turn more (180 degrees) and LOOKED and VERIFIED that the cam is where it SHOULD be.
It's simple. You were half way there. You looking at the dots or what ever doesn't make me feel warm and fuzzy.
Do like I said and VERIFY by valve opening on crossover (overlap) and post a picture of what the rockers are doing. Then you'll know if the cam is straight up, advanced or retarded.
