I remembered my post about the loose lifter threads was actually titled 'loose in the lifters'. I had it mixed up with an old out of date expression 'light in the loafers'.

Re: Valve lash for 59A style camshaft
JSeery's advice a way to go re tightening the thread fit. I also read someone used a punch to "upset" (disturb) the threads on the adjustable bolt to tighten the fit, but suspect that might produce more unpredictable results.
Regarding "prying down the tappets" to get a gauge in, the tappets obviously shouldn't fit too tight in their cores .... be sure they're not distorted and binding. |

Re: Valve lash for 59A style camshaft
Thanks JSerry and all others who have taken the time to give me help. The tappet intake lash reading before I adjusted them were all over the place. One was as high as 0.20

Re: Valve lash for 59A style camshaft
The small holes in each lifter boss are for inserting a drift punch into in order to keep the lifter from rotating while adjusting them. This is not usually done for a stock cam but I would measure the existing clearance and assume that is close to where it should be. Setting the exhausts too close might result in burnt valves, too loose will be noisy. Good luck!
