Our gasket sets contain all necessary head o-rings to run our billet heads. These contain one inner and outer o-ring to seal the outer head and dome to the cylinder as well as one dome sealing o-ring to seal the dome to the outer head. Dome sealing o-rings can also be purchased individually. You will need the head nuts and copper washers to install the head for the first time, though if you are the original buyer of the head we include with them the head. If you would like just the head nuts and washers click here

While it is free, USPS ships slower, so please expect 2-3 weeks for delivery. If you need them faster please select the FedEX option. IF ORDERING MORE THAN ONE SET AT A TIME AND YOU WOULD LIKE THE FEDEX SHIPPING, YOU ONLY NEED TO PAY FOR 1 KIT WITH THE FEDEX SHIPPING, I WILL INCLUDE THE REMAINING SETS IN YOUR PACKAGE.

For example, if you would like 4 sets of gaskets and shipped via FedEX order 1 set of gaskets with the FedEX option, and 3 sets with the USPS option.
