Re: Inline 6 help

'79 and later 250 had the Pulsair head with integral intake manifold and 2bbl carb.
The 292 and earlier 250 and 230 with separate intake manifold and exhaust manifold used a one-piece gasket, but there is a three piece gasket available.
Felpro's intake gasket has their Blue-Line. The two piece exhaust has a separate part number.

I tried these gaskets when I first put the headers on my 292.
THE GASKETS ARE CRAP. At least for use with headers. The exhaust lasted a week. They are crap and overpriced.
Felpro does have a one-piece, but is for stock cast exhaust.

The end studs are threaded into the head. Soak with your favorite penetrant for a day and turn out with a good vice grip with good sharp teeth. You would be doing yourself a favor if you install studs in all the manifold bolt holes.
