Anyone running Supertech Valve Springs?

[///MontereyM3]

Hey guys, is anyone running supertech valve springs with oem valves? I'm trying to do a valve adjustment now that I have the head back from the machine shop. However, it seems like the shims are slightly too large for the valve keeper. I'd almost have to forcefully put the shim in, which shouldn't be the case. Anyone run into something like this before?

Thanks!

I have ST valves, springs, and retainers...you mean the shims seem too large for the 'retainers'? I've never run into that issue w/mine.
