are the heads machined to match the block?can this be done on all subaru blocks ie 2.0 2.2 and 2.5 ect ????

 

[ali burrows motorsport]

just block ... at the minute only doin 2 L .. need a bigger cutting head for milling machine for 2.2 and 2.5 ..

Ali i suppose its too late to do the gas ringing when a block has allready been assembled or can it be managed? And is there a different head gasket that has to be used or is likes of Cometic still useable?
Thanks

best to do when block is stripped ... still using standard type gasket ..

 

[Animal spec-c]

when will it be available for 2.2 blocks?
