Hey guys,hate to be a pain,but i have a t-rex 440cc and can't get this @#$%^& cool head to seal,second time I've put it on and it keeps getting in right cylinder and leaking in between the decks on the exhaust side,right in the middle,now I do all my own wrench en and I'm no idiot,hell I'm a freaking drywall contractor that hangs,finish and paints drywall and I love banshees and working on them.Now I've put together pro design cool heads and never had this much trouble,but this t-rex cool head is getting be a pain in my @ss,TDR sent me a complete o-ring kit and it has 12 o-rings in it, now the big ones go around the decks and the 2 for the domes and the 2 small ones for the for the top of the domes and the little ones for the water necks,so where does the other 2 black and red o-rings go?they are about 2 inches in diameter,do they go to the exhaust or the power valves,and where am I going wrong with.Please help if you guys have any input,I'm about to pull my hair out,and I called DASA and they said torque it at 24 ft pounds,does this sound right,because I did and it leaks,Thanks again guys for listening.

my coolhead had a big one around the deck, one on the top of each dome by the plug, one on each side by the plug hole in the head itself, and one around the dome to seal it on the deck around the piston(these are about 2.75in/dia) Also some red ones for the pipes.

Hey man thanks for the info on the cool head o-rings,but listen to this,I found the leak,its in the casting where the power valve slides into,that's why my exhaust is filling up,on the right side.new set of 72mm and they leak,how many times have you heard of this happening,it just sucks that it happen to me,but the good news is the shop i got them from,called DASA racing and since they were new never ran that their still under warranty and send them in and they would port another set and send them to me free of charge.The shop I bought them off of had them sent to DASA to make sure the porting and cases where dialed in,because he had gotten the engine on an trade,brand new lower end,t-Rex 72mm stock stroke,power valve,full drag port,never put together,and it was one of the first ones they did,because the only numbers on it are P-1,but I pick it up cheap and put it together and ran into this problem,but like I said its all good,since the problem is getting fixed,shipped them off today!
