Has any one found a shop that will send you a modified head and let you send them yours back as a core or what shop is good to go with and about how much it will cost and what kind of boost can that support. Also whats a fire ring.

 

If you are going to take the time and effort to do it, fire ring it. I wish I had.

 

So whats wrong with o-rings? I have never had a problem with them, nor has any of my buddies that have them. Thats all the Big Bad Dodge was running on his old truck.

 

were are you located not sure about o rings all ive ever done was fire rings ive seen them hold well over 100psi and over 70psi using stock bolts

 

Fire rings are good but for most street trucks I'd say that o-rings will hold pretty much anything we plan on doing. Especially with studs.
