Valve / Piston Clearance in 383

Yes.....

Check the clearance with some clay and be absolutley sure the proper installed valve spring height is checked and double checked.


Same basic setup on HP 383 with older 5.09 mopar cam. Used brand new recommended hemi springs and got some minor contact on one piston because I did not verify what the machine shop gave me back. First good run the valves floated a bit and this was the reason. Tear down a few shims on the springs installed wrong and all was well. So double check others work.
