Valve spring install question *searched*
#17
What springs are you going with? Machine shop will be able to do it for you, but depending one what springs and what spring height your using. Each spring has a different seat pressure different spring heights will give you your seat pressure. I would figure out what springs, what seat pressure your going to have with it, and have the machine shop doing it if your having them do it being depending on height your may not have proper shims to get your what your going to need for seat pressure.

Gsc 4041 I believe the PN is...

Ok with that said the gsc should be fine with that said I am guessing your leaning towards the s2 cams.
Maybe I missed something where is the contradiction? EDIT: After rereading the whole thread I don't see the contradiction. I was agreeing with take it to the machine shop and have them do it. I get you have the tool to do so, I have a tool to do it as well but that doesn't mean its done right. Sure lots of people do it I myself have as well but had no idea what seat pressure, and spring height I was running and what it was important. I just threw springs in with stock seats and called it a day. Not the right way to do it and will lead to coil bind and floating valves not that I know lol. (reason I had to redo my head)
Ok, decent spring, honestly I know there are better springs out there, but complete kit. Being I work for a valve spring manufacture those are nice being they come with everything you need. They will definitely do the job for s2 cams if in fact those are the ones you go with.

GSC 5041 are designed to be used with the stock spring seat/shim. You do not need to check these things, it's simply not necessary. As I stated before, you are installing springs that are made specifically for your cylinder head. GSC will have already QC'ed them for spring rate, and free length, which means once installed they will have proper installed height and seat pressure with the OEM shim/seat they are intended to be used with.

This kit is capable of 11000+ RPMS, with as much as 12.1mm lift cams (net valve lift max due to seal to bottom retainer contact). These are a must have for anyone pushing the limits. If you have had problems with valve float or throwing rocker arms this is the spring set that will cure your problems for good.

Yes I am aware of that and yes they are installed tall. Look I am not going to argue they are a bad spring, I just know being i do this for a living. I deal with springs for every major racing event. I run our springs in my own car. What makes me laugh is they say beehives are used in NASCAR and F1 and I will tell you this I make springs for every team in NASCAR and just about every team in F1 and only a handful of F1 people use beehives LOL. Anyways back on subject if that is what you choose good luck hope they do well for you.

Is what's actually funny is F1 cars don't even use valve springs. They're all pneumatic...lol.
I'm not arguing any one spring is good or bad. What I'm getting at is that of what is available for the Evo is all great product. And, most of what is available for the Evo is all specific fit parts (valves, springs, retainers, etc). So measuring installed height (of the spring), and checking seat pressure is an unnecessary step, especially when simply swapping springs/retainers on an OEM head.
