I did not thoroughly clean the heads from the machine shop because they came in a vacuum seal bags and appeared to be spotless when I unpacked them. Is it possible that they were full of CNC shavings?

Also it’s kinda hard to tell in the pictures but it almost looks like the metal is little teeny tiny pieces of spring or possibly shavings as if someone was drilling into some thing and left the bits

Valve seal springs…

Valve seal springs…

You’re a genius you’re right! How in the heck did that happen? All they do is sit down on the little lip in the valve

It isn’t too hard to get the springs to pop out of energized seals. Do the valve springs rub on the seals?

They did not seem to when I installed them but it’s almost impossible to tell now the spring blocks my view.

I'm glad you found the issue! @George B was quick on that one. I couldn't think of anything that would have a spring in it up there until he mentioned that. Good thing they fell in the head and not in the hole

You can’t use the hat style valve seals with dual springs. You just found out why. That’s why I asked earlier if you bought Viton seals. You need this style. The hats on the ones you installed interfere with the inner spring on a dual spring setup.

 

[Rocket Man]

Whatever you do, do NOT install the hat style seals! Hopefully you got lucky. You’ll know when you pull the seals off and see how many got wrecked. Hoping for the best Dan!

You should have received different seats that came with the springs, then the style seals I showed you. The seats and seals are 2 piece instead of the 1-piece seat and seal. I know when I bought my springs from VHP, Roger made sure I had the seats and seals that worked with them and told me the reason. Where did you buy your springs from?
