Springs on intake valves in the ports? 1960 413

Springs on intake valves in the ports? 1960 413 - 07/10/13 11:41 PM

A friend is working on a 1960 413 engine and it has springs on the intake valve stems inside the ports. I've never seen anything like it. Anyone know anything about these? See the picture.

Does it hold a seal on the bottom of the guide?

Looks like someone put seals in the wrong place,if anything came apart you know where it would end up !

They say the engine looks like it has never been apart. It's out of a very rare Ghia Imperial limo. They are on every intake valve.

That car is a very rare, high dollar dude Maybe the Italians(SP?) knew something we didn't know back then

I can't imagine Ghia would have done anything with the engine but who knows. The engines went through special handling at Chrysler. As for having those parts in there, there is not only a risk of broken parts falling into the cylinders but it can't help with airflow. I'll see if I can get some pictures of it disassembled.

That spring looks too new to be 50 years old. I also doubt they had those nylon valveseals back then.
OTH, the valvestem is at least getting lubed...

Here is the latest update on the mystery. It appears that these are retrofit valve seals that were used on Buick Nail Head engines. Apparently Buick didn't uses valve seals on these engines until 1966 which was the last year. Some retrofit seals go on the top of the intake valve guides as normal and others are like this.

They will not be going back in when the engine is built.
