spark plugs & exhaust manifold gaskets (your recomm)

[brans87]

Going to be doing a motor swap in my buddy's 88 k1500 350 TBI and up in the air go with factory cheap plugs or go with a higher end plug? also anyone recomm decent exhaust manifold gasket for stock motor?

Not looking for anything super fancy but this is going to be a crate motor and he wants it to last a while. So thoughts and opinions?

I haven't used gasket on exhaust manifolds for a long time

Using headers? Dead soft copper

Remflex is all I'll use. Thanks Scott!

For plugs use what the factory recommends. These engines seem to run best on them, and I've seen a few issues with trying to run newer style fancy plugs.

For exhaust manifolds, the three piece factory style works well without leaks. I generally get the Fel-Pro brand. I also like that they're easy to install--thread in the bolts and drop the gasket in, as opposed to lining up bolt holes and holding up a one-piece gasket while manipulating the manifold.

Many folks just get the exhaust manifold surfaced and run without gaskets. Headers? Like @bent72 said, copper.

If you have access to a big belt samder you can surface your own manifolds if you are careful. Actually, the machine shop is just going to let them ride on a giant table mounted belt sander anyway. They aren't as particular as an intake manifold, as long as they are flat accross the mounting surfaces front to rear, you'll be good.
