Isky Valve Springs, Thoughts on quality? #1393633 02/26/13 12:03 AM 02/26/13 12:03 AM

These were double springs and obviously much higher pressure when new. In an attempt to get my heads put back together before this weekend I went to the local speed shop and picked up a set of Isky 9005 springs. The price was right and I was glad to support the local business.That being said does anybody have any yay or nay inputs on the Isky brand? I couldn't tell you off hand what my old springs were but the fact they are so weak and or broken after such low mileage is pretty disappointing. I hope the Isky's hold up better and are worth the money. Thoughts?

I was very happy to find that pricing and in stock at that. Sounds like I won't be disappointed at this rate. Last edited by MadMopars; 02/26/13 01:08 AM.

The wierd thing is they didn't seem to be floating or at least you couldn't tell easily if they were. E.T would just drop off. I'll talk to my machinist tomorrow to determine possible reason for failure. Just another reason to dream about how much faster the car will be when I get the motor back together. Thanks for all the input! I'll keep you guys posted. Last edited by MadMopars; 02/26/13 01:24 AM.

I know of several companies that all sell the same springs with different part numbers. Like I said,Isky may be different though. Keith www.dunnuckracing.com

The machine shop wants to use different keepers because at approximately 1.9" installed height they are showing like 180lbs closed and 420lbs open. When the speed shop checked them they were showing 160lbs closed and 360lbs open at my installed height. A slight issue but assuming the the rockers don't hit the retainers I'm ok with using different keepers to get it in range. Then I can swap keepers mid season to get back to where I want to be before they wore in Lol. The speed shop was probably using a mechanical compressor compared to the computerized one at the machine shop. Kind of hard to say which one I trust. Anybody have input on the numbers I should be seeing with these springs? The cam is a MP 557 FWIW. Last edited by MadMopars; 02/27/13 12:44 AM.

Be very careful on the open pressures, check all the retainers lift, ALL 16 OF THEM Then check all the valve springs pressures at those lifts I've got a used set of 440-1 aluminum race heads in my shop now that have a set of 1.64 diameter roller cam springs and titainium retainers, the inner dampener is eating through the titainium retainers The person who asembled the heads set the valve springs up at the same hieght, not by pressure, something is really FUBAR on thses heads The spring pressures vary from 220 to 250 lbs on the seats of the four I have checked so far, 680 lbs at .700 to 750 lbs at .700 and they vary from .010 to .100 from coil bind at .700 lift I can fixed them, I have a wonderful set of tools I have PAC springs phone number Mr.Cab Racing and winning with Mopars since 1964.

Seems like people dwell to much on the installed height specs. Sometimes better to work backwards from the coil bind height and set the springs up. I just got done looking at my Isky tool room springs 9985. Set these at about .100 from bind and saw very little spring load loss(Maybe 5 lbs) after 1200 street miles and some low 9, high 8 second passes. FWIW - have a really nice bench top spring tester that is very accurate and much nicer than the Rimac I use to barrow.

My wife knows to expect a stop whenever we're in Tucson. AND, buy something while you're in there. The prices are righteous and we need to keep those "step back in time" places going! R.
