The wipe was dead nuts....but of course these are my Old heads. I think an .040 shim will cure the new ones, that should give me about .026 allowance for lash or there abouts (I run .016/.018)

These are 1.55" OD springs, Bryce said he had to run lash caps (which he gave me) to clear the Aluminum 1.6:1 rockers he ran on Stevie D's 408 mule. Looks like mine clear fine and adding a lash cap would 'go the wrong way' for my app.
