Not really a problem but rather curosity. So my raptor blew a head gasket after rebuild . havent had the time or money to get a new one but iv found one that i got with a kit awile back but the problem is its for the standard bore. mine is bored to a 686 im pretty sure thats 102mm but i see they sell 102mm head gaskets on ebay would it really matter if i put the head gasket i found on or will i be better off buying a 102mm one??
