Some of those dual springs require the valve guide to be machined for a different valve seal. The springs are also a larger diameter. I'm sure the spring manufacturers have the correct retainers. Check the diameter of the spring. Does the inner spring fit over the valve seal?
Stock valve spring retainers dont fit
Well I started taking down the 454 again to replace the stock camshaft
with a nice mild comp cam and also replace the stock valvesprings with a
set nice upgraded lunati valve springs i bought off ebay.
So far everything went smooth and already got the camshaft in.
I went ahead and started to remove the first spring and install the lunati
spring but It seems like it barely sits right on the bottom plate bearing and
the stock valve spring retainer will not fit on the spring. Does anyone
what valve spring retainers I can buy that will fit? The inner coil on the
spring was flat while the lunati inner spring is a round. Which is the reason
it doesnt fit right.
thanks!
