Tom may have machined all the grooves while cutting the domes and shell, it makes sense he would have the O-ring kits too. He will custom cut If you order enough pieces. I just had special blanks done for my 250 stuff. Once I get the specs all figured out I will have him cut everything all at once instead of having to charge double to set up on my machine for the final dimensions.

I have an O-ringed cool head. Bought it from someone on here or the old site.
-
LRD and Duncan sold a few of the O-ringed heads. They stopped selling them O-ringed due to cylinder decks not being flat and customers Complaining that they would not seal properly. Pro design has always built the heads for other companies. Tom has never sold them as a O-ring unit only head gasket set up direct from pro design. I just ordered heads from him a month or so ago and this came up.

All cool heads have O-rings.....but they seal the dome to the head, not head to cylinder :P
-
Maybe it's just the 87 head that doesn't come o-ringed then. That's what I have.
-
You mean a package like this one Kennerz?

I have a non o ring power head that uses the oem head gasket. The head as no step in it like the stock head, so I know it's got more compression. Unfortunately unlike other cut heads this one doesn't have the cc's etched into the head stay.
-
I got the head from my buddy in Michigan while having my bike dynoed. As far as I know, the coolant ports have not been changed.
-
Did you modify the coolant ports motoman?
-
I'm almost positive Pro Design does not o-ring the head. It's always someone else you buy it from that does it. My pro design head is o-ringed.
-
So who's running a cool head with a head gasket and who's running one with o rings? What type/brand of head gasket are you running if you're running one with your cool head? Thanks!
-
I think Duncan racing has them o-ringed kennerz, I called pro design when I was looking for mine and they said they don't make them o-ringed for the lt500. Or maybe they were just to lazy to put in the order I don't know. Lol
-
Also the coolant passages need to be restricted similar to the o ringed head you received from mhr. They don't weld up the cool head they use epoxy, which over time has been said to not be a permanent solution. Otherwise the use of a normal head gasket is required.
My stock head has been modified like the one sent to you.
-
No they don't come o-ringed from pro design for the lt500.
-
Does the pro design cool head come cut for I rings? Also what's a close to stock 500 cc dome size to go with or what should I consider for dome size. I've had port work done running v2 reeds 41.5mm mikuni and a Q pipe.
