Does anyone know the part number for the header gasket? Looking at Xviper's write up on the Toda install it appears that the number is 18115-PCX-004. The gasket that Majestic just sent me is 18115-PCX-014. Are the last three numbers just a revision number or did me send me the wrong one?

 

It is the right one. You really don't need to replace it either, but to do it right you need to. All of the Honda parts, oart number are PARTNO-XXX-REVISIONNO. So a 18115-PCX is the head to header gasket. -014 is the revsions. Also any part with PCX is an S2000 only part.
