Valve stem seal

#1
In my gx200 build I'm going with stock valve train with 1.3 rockers and 18lb springs from agk.

Do I yank the intake valve seal to gain some installed height and prevent coil bind?

Also I read that only the 160s have the seal...Truth? Are they important to have?

Thanks!

I have a Gx160 and I don't remember seeing any seal and if it did, it's been running a long time without one just fine. I have changed the valve springs alot too from #18's, #26's, #55's.

I have pulled a couple of clones apart that didn't have em either but they were modified. The only engine I have that has one is a Pred 212 and that also the only brand new motor I have ever bought.
