Tom,

I would be interested in a couple pair of the 3.5 x 5
I have what I think are vintage Hooker 4 bolt flange headers that came off of my L78 69 Chevelle.

How many pairs do you have in this size?

Re: Square flange Mr Gasket Header Gaskets
 

On the collector nearest the flange Hooker vintage headers have the Heart w/ HOOKER HEADERS Stamped completely around it about 30 times.. maybe till around 74*75.
Then a Part # & HOOKER on the Head Flange.
Later came the tacked on SUPER COMP or Competition tags.
