Do they make a 310 gasket kit that uses a headgasket? I picked up a stock cylinder that was re sleeved for a 310 and it had a fireball racing cool head. The head is a gasket type and the stock gaskets are to small. Any ideas? Also, it came with an 88 piston so I either have to get a long rod crank or an 85-86 piston. Is the long rod worth installing?
