Hmm, well I was told that superduty heads were good to 35-37 pounds of boost.

Guess it's another example of bad information being very believable when well delivered...

You said valve springs and keepers, nothing about the heads.

Well maybe in my ignorance I'm lumpin it all together. I was kinda figurin when I did studs, I would do springs and keepers, if it's necessary. Figured if the head gaskets were good to that lvl, then it all would be. I figured the gasket would be the weak link there.

You can take a 7.3 above 40psi. It's the peak cylinder pressure that will kill a 7.3 without studs.

The weak point on a 7.3 head is the valve springs. Replace asap. The stock keeper are fine with comp 910's.
