Ahh Yeah I forgot you got that head gasket puff , Iโm seeing a lot of guys starting to use the fire ring style without the grove in the block , If you watch the skid factory Barra build they donโt cut a grove in the block . the gasket locates it like the anthea one . Maby itโs a better option , please send yours to 40 psi for me ๐ ๐๐ my wish list is NOS , 218c and cnc ported head , I just worry about the bullet pistons ๐
