use gasket material (from any auto supply)
also use a sealer (I use permatex copper)
my intake is on second bike and second engine (swapped cylinder, piston & rings)...still no leaks :D
there are numerous threads dealing with gaskets here do a search and add to an existing thread
(let me know and I will delete this one)

you could try checking the carb is sealed to the manifold as well
they tend to leak through the slits on the side of carb
I use a rubber o-ring inside the carb to seal it
if you go that route, push hard on carb when tightening so it makes a good seal
good luck !

did you let the permatex set for a while i usually go with 6 hrs on mine. my brothers has the problem with revving after you let off the gas and pull in the clutch its like the throttle is sticking but ive looked and it isnt

i let that permtex sit for 24 hrs and basically it reves by itself i have the needle on the 4th postion and also 2 warshers under it and the plug is no wet does tha tell u something is wrong lol, but this engine makes more noise like the piston doesnt have a close tolerence comparing it to my other 70 and bascally runs rough at low rpm at steady throotle until u hit the powerband then it smoothens out
