220 Cylinder barrel

Hey guys , I have a 220 cylinder that needs a valve job and my local Napa machine shop tells me that they can do it if I can get the barrel to screw off .My question is how the heck do you get it to come off? This thing is on tight!!!!
 
unless you have the time to build a heat bench its better off to take it to a air boat shop and have it done. you have to heat them to about 700 degrees to unscrew them and then quench just the barrel to get them sepperated.
 
No airboat shops that i know of up where i live in SC. Any suggestions as to where i could send it in Fla. or will a rose bud on a torch do the trick without messing the cylinder up?
 
it wont get hot enough that way and you still have to quench the barrel plus when you screw it back on you have to make shur that the bolt holes and the cylinder are back in the same place or the cylinder will sit crooked on the moter and the exhaust and intake will not line up properly
 
if you get on airboattrader.com you can find loaded cylindes cheap of you can co to services for sale and theres lots of help there
 
Spend $250 and just get a new chromed fully reconditioned cylinder from Tom Jeffords. If all you want is the valves redone then send it to Gary Barber in Plant City, Don George, Mike Thruman, JC Stanley or others that do that for a living. If NAPA can't do it without taking the head off the cylinder barrel, then they can't do it right. They just think they can.
