Who's installed these and checked the height out of the box on stock heads? Is it actually correct? Did you need any shims to get it to the advertised 1.80"?

i'd agree ^^^ still check even on stock heads. and if you're heads have been worked, you won't know exactly what the installed height is.

i had anywhere from 1.805 up to 1.876 and there is no way I would have known that without the mic. It's relative quick once you get going, but I ended up needing to shim about 8 valves.

Yea i agree get the spring height micrometer....it is worth it even for only piece of mind....

My heads have had work done on them and they all needed shims....


Order the micrometer from one of the 2 big companies then send it back when your done.....

Oh also I would order the micrometer for "Beehive Spring" because the retainers on the Patriots are fairly small and will fall down into the regular micrometer....

I should just buy a digital caliper at harbor freight.

you can try that, not sure how you'd setup up the seat/retainer/keeper and hold it all together while you try to measure.

I have a pair of calipers from HF that I use to get close on some things, but not for valve height, you really need a specialty tool designed for this. I didn't feel like spending 50 on this either, but glad i did.

Physically installing them is more than likely the only way. May be extra steps, but it's a $50 difference and just as accurate.

Good luck with that...

Yea there is no physical way to get the caliper in there to measure....have you look at the springs yet? not trying to be sarcastic...

I would just but that micrometer from wicked for $25....that is a GREAT deal and it is exactly what you need and it will be accurate...
