Can you stack the gaskets to get piston to head clearance? If so how much do you think you can get away with?

Call Lubbock Gasket in Lubbock Texas. 1-800-527-2064

While there are opinions for and against copper gaskets, Lubbocks can make gaskets up to 1/4" thick for any tractor. They might need a pattern but they are good people to work with. They also sell different types of gasket material but I am not sure how thick they can fabricate one from these other materials.

If it is a Deere.. U can have Lubbock make you a thicker gasket between the crankcase and block... ( like someone posted below.. just like using a spacer.. but just a gasket.)... JDGnut

If it is a deere 2 cylinder put a plate between the block and the frame have seen as much as 2 inches

I don't know what you're working on but most of the time you can chuck the pistons in a lathe and spin some off the top. Just don't get it to thin or to close to the top ringland.

It depends....The more compression, the tougher it is. The more head studs evenly placed, the better your chance of success. I remember working on a tractor (JD "A") that someone planed down way too much - .125 on the block and .125 on the head, that detonated terribly at low idle. We took a look at it and did to cc'ing & thought the best remedy was three head gaskets, otherwise the guy was going to need a different head. We used the rubber composite gaskets available from Deere and sealed them initially with Hi-Tack, using copper coat aronud the fire rings. When pouring the coolant into the beast, we pre-heated it to 200 degrees and tried to keep a 200 degree fluid in the tractor for over four hours, heating the castings such that a guy could re-torque hot. The gaskets held, but looked ugly. The detonation problem dissapated with the use of AvGas & the guy was happy. It reduced the cylinder compression from 175 to 140. It was a real pain in the a**, though. That is the only time where I've seen such contrivances work with these old tractors, but the car giys really know how to make it happen (even have different thickness gaskets for certain 'wildcat' applications such as this!) When I helped a friend with a 2010 Deere gas (low-power pieces of junk) that he had over-agressively milled, we took the old gasket to a machine shop, where they produced a .030 plate that took a gasket on each side. Worked fine and probably will last longer than the "A" setup....I hate to say it, but it's hard telling without knowing for sure, if you understand what I'm saying....LOL

are you saying thst at 140 you still had a detonation problem that was cured by avgas sounds like avgas was the cure all along

See the expanded detail below - AvGas didn't cure the problem initially, not enough octane. It would run with the timing retarded on Turbo Blue, which is 114 from the pumps around here. Only problem is that Bule is around $6.50 / gal, while AvGas is $1.70.

Didn't you know how to time it?

Ahh - A master of the obvious! Yes, I do know how to time the engine. The problem was that the head had a few hot spots that couldn't be dealt with. The machine shop used a scope on the firing chambers and figured that the casting was poor, as thin cast was probably overheating. The guy tried to smooth the chamber up some before he brought it over, carving it down considerably in some areas. It would run without detonation if the timing was retarded approx. 20 deg. once it was warm, but made no power. In addition, the dip bolted plates to the top of cast pistons, which also caused problems. It was a charity case on my part - the guy had shot his wad on what he had already done & it was an attempt to make it run without spending significantly more money.....Certainly not the way we do things from scratch...

Sounds like the "plates" on top of the pistons couldn't disipate the heat away like a one piece piston top. The plate(s) must have been acting like a model airplane's glowplug to case detonation with AV gas & only 140psi cranking pressure. Flame travel was likely impeded as well while trying to get across that large combustion chamber.
