I would go ahead and do screw in studs cause it's likely cheap while the heads are off and just good insurance. Plus they'll be there if you do a real cam and springs later on and wont have to f with it with the heads on the motor worrying about metal shavings and such.
This engine isn't getting anything done to it beyond this and long tubes. I've got a stock roller block sitting in the shop that will get built. I'm just tired of looking at these heads sitting on my bench and contemplating what to do with them.
With those old school rockers you can get away with more variance in pushrod length since they aren't fixed position, they are essentially adjustable. Be good to check the wipe pattern though to see if the pushrod length is real far off.
You ever adjusted that style rocker with the engine running by the way? I have it's wild compared to the new ****. My father in law has a set of valve covers he cut the tops out of for doing it so oil doesn't go everywhere
Can't say I've ever done that. Done a few things with the covers off but not adjust rockers.
Easiest way to do this style. Pretty common to do it that way. I'm sure there's a right way but I tried that, and with the engine running was far easier and I got better results the last time I did it.... 15 or so years ago lol.
The stock Vortec pushrods will be way too short but your originals will be pretty close. The rockers on a Vortec are identical to adjust as any hydraulic cam small block since 1955. Running is way to messy lol.
I used to adjust them while running also, I used pieces of tin foil over the oil hole on the rocker. Now I use the zero valve lash 1 full turn method, works good for my applications
