The stock gaskets won't limit any airflow now that they will be worked over?
I need the ARP bolt and studs or just the bolts?

 

 

No because the stock 6.0 gaskets are 4.04 bore IIRC, they will do nothing to hurt performance and if you have a hook up at a dealer arent oto bad in price ocmpared to cometics. Bolts will be fine I dont htink you can install studs withouth removing the motor. Bolts will be fine.

 

FWIW my 408 is getting stock gaskets this time around.

You can do studs with the motor in the truck.

 

How?? teach me Obi-won

 

When I pulled my heads I removed the studs first. Passenger side I set the new head in place, then installed the studs, then the nuts.

Driver's side I installed the studs first and was able to fit the head over top of them. I didn't try the passenger side like that, not sure if it would have worked or not.

 

Cool, i think i'ma grab the sstock gaskets from Thunder racing since i live close by and there like 30something bucks.
