Which valve springs?
Hi guys, just in the process of rebuilding the 781 heads I bought for my 454 and have noticed the valve springs will not transfer over from my old peanut port heads!
The stock springs on the peanuts have a cage type support around the outside and the original very old and tired springs from the oval port heads are dual with no cage!
What would be the most cost effective replacement spring that would fit the 781 heads?
When I stripped the 781's down half the springs had rotating thingy's on the bottom(technical term!!!) and half had shims! What gives?? Do all the springs need to be shimmed?
If so, what depth am I looking for?
Thanks in advance and apoligies for my technical terms!
