Are they leaking from around the gasket or out the breathers? If their leaking out the breathers just cut a shop rag in half and put half in each breather.

We put a thin bead of silicone(SP)on the gasket before putting it on.

use a felpro cork gasket with those long holder things under the bolts. But do not over tighten, just get it a little past snug.

We use scotch brite pads rolled up that way nothing to fall into the motor and nothing that can get completely plugged. Just dont' use the ones with sponges on them.

Get a good set of cast aluminum valve covers and weld a set of baffled breather tubes in. Use 3m weatherstrip adhesive to attach the gasket to the valve cover only. That way you won't have to replace the gasket everytime you run the valves.

I've run these for years and have never had a leak.

I have two sets of cast alum. covers that i'd make ya a swingin deal on. one style has a crossover welded in, the other just has a breather on the left side..
If you are interested let me know and we can talk $$ but i'm sure it would be a pretty good deal for sure, I have no use for either set anymore as shafts dont fit under them.

the two previous posts have it right. Cast Alum covers with thick flanges work good , last a long time. Cheaper, thinner sets work for a while,then they will warp and start leaking. You can spend a little several times or pay more...once.

just like mentioned above, aluminum covers with thick flanges are about the only way to prevent leaks over the long run. The cheap steel covers will work for awhile, you just have to be careful not to overtighten and distort the flanges, once there tweaked there bound to start leaking.

I had good luck with the cheap tin valve covers when I used the blue neoprene rubber gaskets from Speedway that are reusable. They are plenty thick and conform to any irregularities.

I agree, alum. is the way to go. Anything MOROSO makes is good quality stuff.
