Re: Comp valve spring trouble
Sounds like you might need to have your heads machined to work with different seals for those springs.

Uh, yea. Vortecs have notoriously tall FAT guide bosses. Bring the heads into your local machine shop and tell them what you've got. Common as the day is long. They'll know exactly what needs to be done.
