OEM or Racing Beat for everything if you want it to last. The 1st gen section has a nice thread on good vendors, btw.

Exactly. If you continually blow gaskets or have blown out a gasket in the past, the flange must be resurfaced. A warped flange will blow gaskets constantly, and a blown gasket will allow hot exhaust gasses to erode the flange material so that when you replace the gasket, the flange is no longer flat.

Also the TII manifold cracks after 20+ years so you may have some decent sized cracks that are causing the gaskets to pop.
