What Are You Doing To/With Your Car Today?
Today I removed the lightly used Comp 953 springs, retainers and 10 deg locks from the iron heads, and transferred them to the ported Speedmasters after installing new valve stem seals. Then I started setting up the ductile-iron rocker valve train with studs and aluminum hold-downs.... the positions are not even close to the iron heads that had steel hold-downs and bolts.
This is the disadvantage of a single rocker shaft system - all the pieces on (up to) half of the shaft need to come off to change one shim... not to mention those rocker arm separator springs like to fly across the room! :rolleyes: Oh well, unless I change rocker arms, I won't have to do this again.
