I am having valve float over 700 and need to switch out. Was thinking of some dual PAC springs.

The BTR dual valve springs have always worked flawlessly for me.

Any model numbers on those? I'll be switching within the month so I want to make sure to look into the proper ones.

You need a part number for a single set of springs? I guess there is steel or ti retainers as an option...

Most companies make different types of springs, unless they are different than most companies. Excuse the ignorance on the subject.

Go to tooley's site. Look for the set for around $220 with the light weight steel retainers. They drop in the LS heads no muss no fuss.
Mine see 7000+ no issues. I have stock rockers.
All bets are off if you have rollers. Then it would be best to call them.

Our SK001 .660" lift dual springs shimmed to 1.750" have been used in combinations making upwards of 1600 hp at 7500 rpm.

224/224 .595 114 cam. Stock rockers and Comp dual springs. I don't know exactly which dual springs though just that they are comp dual springs. I bought the car mostly built and I am trying to fix all of the screw ups.

Valve float with boost usually just hangs up at a certain rpm, not missing/popping or anything crazy. Try lowering the boost and see if the rpm carries more.
