Something I should really stress is that my install was part of a cam install. I have no experience with installing the roller rockers alone, as a single mod. I cannot say if the springs I used will work with a stock cam setup. Maybe someone else will step in.
I also changed to trickflow hardened pushrods and swapped the lifters to LS7's. I had to measure for pushrod length and spring heigth. I used the TDC method for adjusting for zero lash.
Here's a link to my cam install if anyone is interested.

I bought the springs through Lloyd Elliot when I bought the cam.
Here's the link to Patriot Performance where the springs are sold.
Glad to help.

I pulled the cover off the passenger bank first, and felt the pushrods to see which could rotate, then removed and replaced the rockers from those with the nuts turned just tight enough that the pushrods could not be hand-rotated, fired up the engine and adjusted them 1/4 turn down past where the ticking stopped, then locked them. Shut it off and found that the pushrods associated with the rockers I hadn't changed were freely rotatable so I swapped out the rest of the rockers, fired it up and adjusted the same.
Ditto for the driver's side.
I would have done the TDC deal but wasn't in the mood to manually rotate the crank, find a socket for the breaker bar, raise the vehicle, work around hoses, etc. I got lucky with the crank position on the drivers side and was able to change 6 in one shot, the remaining two after I shut her off.

This may or may not seem like a really stupid question, but will this 1.6 rocker/ 7/16 stud / pushrod setup work for a L98 engine, on a 88 corvette with the stock cam?
I am considering my first bit of non-bolt on work, and I don't think I have all the skills/general knowledge to install a cam yet.
Have read all the precautions for pre-oiling all the parts and keeping the area very clean. I have been researching it, I just havn't found alot of articles involving the L98, just want to make sure.
