Default question about springs(in the head)

do you think it would be overkill for me to get dual valve springs for a baby cam ie tr224? would i have to worry about too much clamp pressure?

Dual springs are not necessary for that size cam.

I ran Patriot Golds for almost 25K miles on my TR224 with no problems and the car ran awesome and made good power. Checking pressure showed only a few psi drop after 25K miles. Previous springs were bluestripe 918s that were down 20-25psi after only 10K miles.

I say use a good dual spring.

I had Comp 918's on MTI's Stealth II cam (224/220 .580ish lift). Unfortunately, I had one of the bad 918 batchs and an exhaust valve spring broke after 4000 miles. Consequently, piston hit the valve, blowing the motor (two holes in block, piston destroyed, rod in many pieces!).

Had I used a double spring, the motor might have survived. I built a new motor and used Patriot Gold double springs. It's just good insurance.

Always run good valve springs. This is not an area to use bargain parts. I prefer Crane 144833's, PSI 1511's, or PAC 1518's.

Please provide your basis for this statement?

To the OP:

You need adequate seat and open valve spring forces for the cam. If you are staying with beehives, I would agree with the prior post that PSI 1511's or PAC 1518's are the best bet and due to the material processing they will provide excellent valve spring life. As for duals, then the Patriots would be more than adequate.

If you error on seat forces with valve springs, always error on the high side. The low side can float the valve train or cause valve bounce both of which can result in major problems down the road.
