The lash is checked between the roller tip (assuming you have roller rockers) and the valve stem.

I cant believe I wrote that,yes yes I mean valve tip whew good save!

The fact you have stud girdles will make lash adjustments a bit more difficult. You are correct about the 2pc covers, I don't think they will clear a stud girdle. When adjusting lash with a stud girdle the first step is to loosen the gridle at the rocker being adjusted. Then set the lash on that valve. Then re-tighten the girdle and re-check the lash. It may be necessary to then go through the same process again due to the fact the stud girdle may alter the lash when it is tightened up. If you really want the hot set-up you could get shaft rockers, which will likely require new push rods. Shaft rockers will clear the 2pc covers and lash rarely needs to be to be adjusted due to the design of the rockers. This is a pretty expensive upgrade, but well worth it in my opinion when running solid rollers.
Good Luck!!

why solid lifters????



cause wette vette told me i would get hot chicks with a solid roller


Solid roller in my sbc, whole lashin time is probably a hour for me. Adjusted once when cold and new, adjusted hot and never touched them all season. They are loosened up right now so get to look forward to lashing the valves the first time i get the boat out

gotta love hot oil mixing with the blood on my knuckles LOL!

How many hot chicks did that solid roller pull for ya!!

You can also get a "bridge" (not sure what they are really called) for the lower 4 bolts on a standard valve cover. This piece allows you to only use the outer two bolts on the lower side of the valve cover, so you can remove them without removing exh. manifolds.........I've got 'em and they worked great. I changed my solid roller setup to hyd. roller setup (cam, lifters, pushrods) with no measurable change in power - boat ran same speeds and rpm. But now I can run lighter springs, and don't have to "adjust" anymore.......
