Valve stem seals for 429?
Hello!
I am rebuilding 429 for 64 DeVille and got Felpro head gasket kit including valve stem seals. Is it recommended to install those even though they are not originally used? O-rings will be installed of course.
thanks in advance!

Hi Matti,
Yes its recommended. If you are able to read Swedish you can get additional information from TA Motor (best Company for Cadillac parts in Sweden).

Thanks!
I am rebuilding it all by myself, with shop manual and other instructions. I have all the time in the world to get it right.
I am using original cam, crank, pistons, lifters, push rods, block, heads, valves, rocker arms. I need to replace 3 valves and 4 rocker arms only. Plus oil pump gears. New rings of course. Do I still need to do the break in run?

My concern is if the valve stem seals stay in the valve guides because they were not there originally. Are those 429 valve guides designed to keep stem seals in place?
If seals get loose they could create problems under rocker cover. I wonder if anyone in this group has added them.

1963 RHS A/C kick panel - photos needed

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?
My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.
Many thanks,

Edelbrock Carb Block off Plates

Hey guys,
I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…
