dual valve springs
On previous installments of valve springs I have used single springs but this last time because of the cam, we use dual. On single valve spring installment we pre-assembled with the valve and valve guide bushings and slip them into the valve guide bushing bosses. On the dual valve springs, this cannot be done because they are larger than the valve guide bushing bosses.Do we just place them in the valve lifter gallery and assemble them there with the valves?Keep smiling, it only hurts when you think it does!

To use double valve springs,you have to machine the valve guide boss and use teflon seals.you can buy a seal cutter for $40.00 is that what you mean,If your not going to do this a lot may be cheaper to have a shop cut them for you.A set of seals and installing tool is less than $30.00.is that what you were asking.

I ran into this problem w/ my 200 6.. I have a $80 set of springs and retainers I can't use. nobody had the 5/16 tool and were going to make me buy it if I was going to have them done... I ended up doing a little experimenting and used 302 ford intake springs w/ 302 2 pc intake retainers, w / 200 ford I6 centers.
the 3/8" or 11/32" cutters are very common tho. I'd be certin there a dozen places in Auburn that can do themYou don't know what you've got til it's gone

So Denny What I'm getting from that is that the double vlave springs don't have to be used because of a bigger cam, only if theres a blower involved. Will do some more research on it. ThanksKeep smiling, it only hurts when you think it does!

cam will also last longer on a lighter spring. the coil bind, and max lift is all that you really need to worry about.You don't know what you've got til it's gone
