%$#&* Hooker Headers!

[71Duster]

I pulled the heads of this winter, I knew the leaked abit before but nothing to serious, bought the new fel-pro raceing header gaskets and they leak like a sive! Tightened and re-tighened the bolts but b oth sides leak bad. I didnt like the way the flanges where made on them with the raised sealing edge. Are there any gaskets I can use untill I have the cash to buy some TTI's?

try doubling up the gaskets. has worked for me

In most cases, the flanges are warped due to us overtightening, so they dont leak..I always use the Mr Gakset Ultraseals, and I use flat file to remove any high spots..Do not use any silicone on the mating surfaces, only on the threads of the bolts, and tighten for the center two out. I also will replce the supplied bolts with either allen headed, or std cap screw styles that are about 1/4 inch longer, so they dont weep coolant. if you really tighten them so they dont leak, you bend the outer flanges every time. the stage 8 locking bolts are the ticket with aluminum heads..

A goos set of HP manifolds will cure all that ails you. Sounds so nice when the exhaust doesn't leak.

With my cam and set up I need The heades, and the 68-69 HP manifolds are getting pricey these days. I was talking to Don@FBO today and he has hooker supercomps on his Fish Fry and sold me a set of Cometic header gaskets. Gonna see how they go.

I hear the cometics are THE way to go.
