**help! I Need A Head Gasket To Suit My Rb22 Build**

[mattR32gtst]

I have built the rb22 bottom end with Rb25 crankshaft and rods with 4agze 81.5mm pistons i now need a head gasket to suit my questions:

where do i get one to suit the 81.5mm width ??

what thickness do i need ??

Any help really appreciated as im struggling now

[STATUS]

use a rb25 or rb26 one. Otherwise HKS or tomei do a special gasket.

ive used RB26 ones (customer could not afford a 82mm) in the past without issues. I do have a used 82mm Tomei or HKS rb24 gasket here somewhere if you get stuck.

just a stupid question....... if you can use an RB26 gasket on the custom RB2.2 block

can you upgrade to an rb26 head also?

just curious because i know the rb26 head flows wayyyyy better than the rb20det head

yeah it can be done, rb26 has larger head studs/bolts though.

So rb26 bolts/studs will have to be used ?
