Replacement for Patriot Gold springs? So, my old CNC ported 241s have a set of Patriot Gold springs on them, and after they've been sitting for 13+ years, I don't trust them to be any good ( they weren't that good to begin with, apparently ). However, the titanium retainers and locks are perfect, so why toss those? Does anyone know of a spring that will fit with these retainers? I'd rather reuse them if I can.

You could measure the springs and then use those measurements to find a spring with matching dimensions, pull the existing valve springs and have the pressures checked, or just buy a new spring kit.

EDIT!!! IDK how many miles you have on your retainers, but why not just replace them, too? Last I checked, maybe a year ago, Summit and Jegs had the 1905s with Ti retainers for around $325.00. Can't go wrong in my opinion..

The retainers have under 1000 miles on them. I scattered my engine in '09 after a full rebuild, was completely pissed about it ( the block had porosity issues in the oil galleys ), so I stuck it in storage and it sat that way until I started tearing it apart last year. So a few of the valve springs sat in the compressed position for over a decade. Whether that hurt them or not, I don't know, but I don't want to trust them in my new ( and far more expensive ) build. Just trying to save dollars anywhere I can. This isn't a junkyard build, but it's also not a blank check build. Every little bit helps.

Just a thought here…Ti retainers have a short life span compared to steel. If this is a build that you really don’t want to get back into in the not-too-distant future, I’d go with steel. The Ti will only help you above 7k rpm anyway, so why chance it? Sell the Ti stuff and go steel if you want it to go the full distance.

I understand that titanium has a lower fatigue life than steel, but I'm assuming I'll replace them when the time comes. And I very well may be running 7000 RPM + when this build is finished. As I said in my cam grinding thread, I simply want to try and salvage my investment. I don't know about everyone else, but I don't have a money tree out back. I still have about $8-10K just in parts to purchase to get my Formula back on the road. If I can save a hundred bucks here and a hundred bucks there, it adds up. My engine had 1000 break in miles on it when it threw a rod. It was 100% brand new internally. I can't imagine just scrapping it without taking good, usable parts off it first. As for needing .660 springs, I didn't say I did - Just that I want to find springs that fit these retainers. I may not even use them with this new build, I have 3 LS powered vehicles and will likely have more over time - Having parts like this on the shelf seems like a good idea to me.
