Would anyone happen to know where If at all you could purchase a set of the tooling required to O-ring a head and or block. I wouldn't mind trying it for myself it can't be much different than grooving a block in a semi engine for cylinder liners and being a diesel mechanic I would consider undertaking the work. I just can't seem to get anywhere searching for the tolls to do the job. Plus i'm all the way on the east side of PA and don't feel like paying an arm and a leg for shipping a cylinder head plus buddies of mine would also do the job if they didn't have to wait and ship the heads etc. and down their trucks for awhile any help is greatly appreciated.
