Installed the Patriot Golds today. Question I didn't trust the 918s since i had the bad batch the first time. This second set was fine when i took them off todat though. Anyway i installed the Golds today and I was wondering , do the dual springs seem to make a little more noise than the single spring? I may be just all in my head. 
I have been running the stock pushrods so do i need to get the 7.4s since they are a tad bit longer than the stockers? Also what kind of a break in is required for the Patriot duals? I drove around town for 15 min and then went home. I never hit above 2k

What I have usually done is to give at least 3 full heat cycles on springs before going over about 2500 rpms. I haven't really noticed our PP Duals being any louder than the old single ones we used to have.

yeah heat cycle a few times,My ppduals seemed less noisy compared to my 918's actually..And i would even go over 3k rpms until you get hardened pushrods.Those spring pressures are probably the limit for stock pushrods..thats just asking for trouble.

If your heads are bone stock unmilled and you have stock head gaskets (if your heads have never been off) then get the comp 7.425" pushrods..
If you have milled heads say .020" mill and a .045 cometic head gasket like i have then run 7.4" pushrods..thats what i have and it runs nice and quite.
This will kepp your preload very close to stock specs.

Talking with a few spring experts before, they've stated that the new chrome silicon spring material does not require any heat cycling. Install, get hot, hit the loud pedal.
Traditional spring material requires a heat cycle or two.

I agree that everything ive read on the Cr Si spring material says it does not need heat cycles, only that it needs to be warmed up every time before you take it to redline. If you dropped your car off at a sponsor for the install and a dyno tune, theyre not going to keep the car there the extra day or two heat cycling the springs. Theyll just throw it on the dyno and tune it up as soon as its put back togather.
That being said, i gradually srive the car harder and harder over the course of 5 or 6 drives, starting with a sedate drive once around the block.
Duals do tend to be a little noisier than singles. Afterall the springs have a slight interference fit which is designed to help dampen any harmonics. Its known as the "sewing machine noise"
