OK the 626-16 locks are 4groove locks and most mopar exhaust valves use 4 groove. Some intake valves only have 2 grooves so you will need the 627-16 locks they are 1/2 two groove and 1/2 four groove. You can't use the stock 7* locks with 10* retainers

So with the 627-16 one half of the keeper is 2 groove and the other half is 4?? Or it gives you an option of getting complete sets with either the 2 or the 4??
Im wondering if the silver 7* ones(if thats what they are) are causing the valves to sit lower...thus the different installed heights of the valve springs?? This in combination with the retarded timing on the crank will cause valve to piston slap.

73abodee, I cant believe we put enough tension on the ratchet to cause bent push rods!! Weird, we didnt just reef on it, I aint a 'tard, I know enough to stop when something jams. Engine is on the stand, so everything is accessible easily enough...oh hey....I just thought of something....take a look at the pics where I show how close the rocker shaft is to the spring...I cant remember if that valve is the one with the new or old keepers, but if it is the old keeper, then the valve would be sitting lower right?? With the valve lower, the rocker arm has to come down further which would put the rocker arm closer to the valve spring right?? New keepers in there, would lift the valve up a bit.... Ok im going to bed now cuz my head hurts :banghead:.... dad is just about ready to give up and send the engine to a machine shop...this is disappointing as I feel like I let him down...its a simple frickin cam swap....my god I took apart my 383 sandblasted the heads, did a newfie valve lap on them, re-assembled it and it ran perfect..
