"You can take it to a radiator

"You can take it to a radiator shop for boiling, but I suggest you are better off by buying a new one. The results of boiling a corroded manifold are usually uncertain and more often than not they don't last afterwards. Here is a link to the Sierra version of the exhaust manifold that fits your engine.

"I second what El say's. O

"I second what El say's. Over the years it's always been a gamble to 'boil' the manifolds. Bite the bullet and get a NEW one, No gamble there. I also like to use the OEM exhaust gaskets. The after market ones seem a little to thin for my liking. They are not that much money, $5.00 or so a piece, but to me, money well spent. They are brown in color and a very thick material."

"Buy a new manifold. After 2-3

"Buy a new manifold. After 2-3 years in salt, remove and clean that one. After five years, lift the manifold and demonstrate how far you can throw it."
