I was just sitting here thinking about a setup I've got a in 79 D150. It's a got a Magnum swapped in with Edelbrock Cylinder Heads. According to the prior owner they have been ported. With that being said the headers being used are TTI B/E Body headers for a small block application. Seems some people say the TTI gaskets are questionable in quality while others say use Remflex which are thicker and they have gaskets for this application anyways. These look a little thin and trying to determine if I have a leak due to these gaskets anyways. What are your thoughts on the TTI provided gaskets compared the Remflex?

These look a little thin and trying to determine if I have a leak due to these gaskets anyways. What are your thoughts on the TTI provided gaskets compared the Remflex? Tti are junk, remflex for 340/360 or magnum may not work, they would not work for me, with edelbrock magnum heads as the head bolt surface relief is way too big right between the 2 center ports, leaving only about 1/8" sealing area. 340/360 headers have a different shape than magnum heads on the bottom of the port, right where the sealing area is small, magnum heads are filled in there, the header port will hang below it. I did not try reflex 318 gaskets, they may work. So far the only gasket I have found that fits this head and header combo with sufficient sealing area is edelbrock 7237. You will need to lay the gasket on the header and grind a little...as the ports are not the same. Stock iron magnum heads are no problem, edelbrock magnum heads are. One other issue at least for me is the header flange are ground so rough I don't think they will seal long term, will be fixing that before I try.

None. Ultra copper rtv and never looked back. You may be right, but how long would that last on a 1/8" sealing area.

We have had many combinations come though the shop and IMO the most critical factor is that there is adequate material for compression between the flange weldment and cylinder head surface. IE: if the flange "seal/raised weldment is too small for the port opening it's not going to seal regardless of what you use. The same is true if the weldment in too large for the area it's clamping to on the head. The weldment should be the same size or slightly larger that the port opening all the way around. The gasket should be completely clamped between the two surfaces with no thinly clamped areas like the corners. Hedman seems to go out of there way to make their weldments as such you can only use their gaskets If you really want to have fun look at all the different sized / type of openings and gasket offerings for small and BB chevrolets. Then you throw in all the different port configurations offered by different cylinder heads and it's enough to raise Charles Manson form his grave and appear sane. We have had the best luck with the graphite looking gaskets from Fel pro and Mr. gasket. We also had to make an interface plate using two gaskets in one situation AND just an FYI: They do sell the material in sheet form should you need to make your own as we have done more than once

Bought mine when they were CPPA That was the 90s.Used the cheap gaskets that came with them They were good for like 4 years.Then changed heads.Used Mr Gasket ultras that set lasted like 8 years Only reason they were replaced was head swap. Probally could have reused them as my kid did on his 413 .This last set has been on at least 10 years and still going strong.For the price they cant be beat.Used them on my Jeep and my Mopar SBs also reused a few sets with no problems.Rocky

Thank you all. I bought the truck with this combination currently in it. Gaskets look question with the sealing/mating surface so I'm entertaining trying a different gasket.

Another vote for Remflex. They worked for me on cheapie headers when nothing else would.

no matter what header, gasket, or cylinder head combination, i always cut the flange between the tubes [first, center pair, and last one] then open one of the bolt holes at least two sizes on each tube "flange". this helps tremendously with gasket, or high temperature RTV sealing. it allows the tubes to move around a little during operation and cooling, thus helping to prevent leaks. i stole this idea from member Mr. P-Body many, many [did i say many ?] years ago, and it just flat works ! [you still need a good sealing bead on the tubes that is the same, or bigger, than the head opening, as has been brought up previously]

Thank you. I will take a look at the Edelbrock gaskets as well. Any gasket that lists the port height more than 1.500 is going to get marginal around that center head bolt area. Be careful about what jegs and summit list for size as they are wrong a lot. Go the the manufactures websites. Stay away from any gasket that has an o-ring around The port, it will land off The head. The trick flow small block heads have this smaller raised exhaust port but have a ton of material left around the center head bolt hole, edelbrock kinda screwed this up, no reason for it. I have welded on the headers to make it fit better... what the bottom really needs is the head welded to get more sealing surface.

For the head and header combo you have I have not found a remflex that will work. The hole in the gasket is to big. The only gasket so far that will seal that center port area properly is the edelbrocks. If they ported the exhaust it may be even worse. Tti small block headers do not fit magnum heads exactly right, just make sure you check that area. I ran TTI headers on my magnum 360 crate engine with remflex gaskets for years/60k miles and not issues.
Facts are stubborn things.

I used the Mr Gasket Ultras on my car for the last 8 or so years. Even reused them a couple times when I changed or freshened up the engine. I put my hooker fender well headers back on to see if the car would pick up and ended up having header leaks. TTI has the nice thick flange and are one of the easiest headers to keep sealed that I've used.

I have been very pleased with the TTI gaskets. I have had one leak in 6 years. I have re used the one on my passenger side many times due to transmission trouble I had for awhile requiring frequent trans removal(and passenger side header).
