I have read other threads about gaskets, but the sanderson directions say i do not need gaskets and just apply permatex px82180 ultra black silicone. I thought we were supposed to use the permatex copper sealent, block to gasket side only. What do you guys think, and thaks in advance for your help.
header gaskets

Head gaskets have a definite thickness to them and it is important that it exists for compression and also so that you intake manifold lines up properly. Unless you have everything remachined, I think you need to use them.
Exhaust manifolds don't need gaskets, though. Is that what you meant by any chance?

OOps. I just saw you said header gaskets, not head gaskets. LOL.
I used copper RTV for my exhaust manifolds and there aren't any leaks. My engine rebuilder told me about it. He told me to just do a thin amount then torque. Wait about 12 hrs then torque again. He said that the exhaust gaskets will need to be torqued over and over. But, that's for a big cast iron manifold. I have no idea about what headers need.
