psi 1511s as recommended by advanced induction are top notch. reason you dont hear much about them is the $250 price on them. pac1518s and pac1218s are next on my list. have had them both and both have performed without any issues. presently running 1511s as upgrade to pac1218s i ran before.

 

Brian Tooley valves springs is what I've been using. $299, titanium locks and retainers, 155-160 on the seat. He also has some that speed inc. sells for $219 that are similar to prc golds. Steel locks and retainers, 155-160 on the seat.

 

I am happy with my Patriot Gold Duals. No valvetrain noise from them.

 

Thats good to hear, that is what I had put on my 317's for my project.

 

i've never had a problem with patriot gold duals in the past 5 or 6 years. here recently a buddy broke 2 golds within 6 months. he got a full replacement set of golds and found this when he pulled his springs. old next to new:


i would say he lost a little seat pressure!
