Get yourself a valve cover and cut a opening in the top so you can run the engine and use your feeler gauge to check the lash while the engine is running. Cut the opening high enough so you can get a socket on the rocker arm to adjust. The valve cover keeps the oil from running out over the headers. It's a lot more accurate and easy to do this way. Be sure to use a gasket also.

I checked the specs on this cam and it says .028. Seems kinda loose compared to yours. I’m using stock iron heads and aluminum roller rocker arms.
I'm running aluminum heads. They require 0.004" tighter lash than cast iron. Cold lash is going to be around 0.006" tighter than hot lash, as well. After you get them set hot, let it sit overnight and re-check them all cold. You get more consistent readings cold and can use that clearance in the future so you won't have to lash a hot engine again!

Merry Christmas!

Thanks for the suggestion. I do have a set of cut open valve covers I’ve used on hydraulic cam adjustments. I’ll have to dust them off.

I run a solid cam in my 65 with a cleveland. Set the lash at .22 cold and never had any issues. But clevelands are supposed to be set cold.

Hey Joe!

The cold lash comments I made were for my set-up only. Aluminum, steel and iron (heads, valves, rockers) all react differently to heat and expand or contract at different rates. Hope that comment wasn't confusing, it can be read two different ways. Needed to clear that one up a bit. :D

Thanks!

Thanks for clarifying Joe. I’m going with the Isky recommended valve lash for my stock iron heads- .028”. See how she runs like that.
Thanks again!

I think if I were on the track and saw THAT in my rear view, I'd just pull over and let it pass! :shock: :lol:
