Valve seal guides different?
These are PP 5.3 heads about 2 years old. The valve seals on thesze heads are not a metal body with rubber insert. They are plastic with clamp that goes around the body of the seal to hold it to the guide. Now the guide is not a straight and smooth guide like the stock guides. It has a dual diameter and the upper part of the guide where the seal sits at has threads on it, maybe to grip the seal. Beneath the threaded part it has a step and steps up to a larger diameter.
I was gonna use the entire contents of the new gold spring kit but the bases wont fit over the guide thats in these heads and Im not sure if the seals in the kit should be used on those guides.
The seals will work on a stock or bronze guide. The bases we send with our kits are for the stock guide. We have a bases with a larger ID for the bronze guids. Send us your shipping information and we will get them out to you.
