Header Gasket Question

[73StangCoupe]

All,

I'm looking at buying and replacing my header gaskets and I have a question. I have a 351C 4V, 4 speed with hooker competition headers.

How can you tell what size the ports are and if the ports are round or square? Most of the sites I'm looking at are selling 1.78" square port and 1 3/4 diameter round port. I've got some pixs of my headers.

If you have 4V's head so you need the appropriate gaskets, there are only 2 choices, 2 V's or 4 V's.

For 4V's

I have tried several types. With hooker headers go with their gaskets.

Also, get yourself some stage 8 locking bolts. Here is a little write up I did on them. PITA to put on but no leaks.

I run the solid copper gasket and have had a lot of good luck with them. Seem to seal much better than a stock paper gasket. And they are reusable.

I am trying some graphite ones that are very nicely made and heavy looking. While my headers and heads are both nice and square, I wanted insurance.

Thanks for the replies and the advise. So how about these...

I took a good look at my headers yesterday, I'm thinking its going to be a bit if a pain to get all the bolts out. Is it easier to go in from the top or the bottom? Thanks again...

I should read twice before answer, I think it's better to go back to english courses.

Sorry I'm french.

It is not an easy with our big 351-blocks... ;-)

I ended up going from the top - from the bottom it is too less space on the drive's side! I know it is a lot of fiddling but once you had it done a few times it goes better from time to time. Let the outer two screws the last ones you unscrew. With a good 4V-gasket you could attach it without removing them because of the two 'hooks' at each end. But the total remove is better for cleaning up the surface with a razors edge or something like that. Hook the headers up with a rope to not bending them too much against the bottom...

From the top works. Go with the hooker gaskets. Use stage 8 locking bolts and be done with it.
