Remflex2008 Round Port Exhaust Header Gasket

These are hands-down the best gaskets I’ve ever used on an LS motor especially when you have that small leak you need to get rid of these fill the hole(s) leak(s) perfectly and immediately! Effectively fixes pesky header to heads exhaust gasket leaks! I actually had the right rear cylinder hit or bolt break off in the head and was able to use the doorman bracket to install this new gasket the crutches in there perfectly along with the doorman repair kit bracket the bolts directly to the block itself and the rear of the head to avoid having to pull the head off and remove the broken stud from the header bolt! I would recommend this to anyone who has those issues with your header bolts potentially breaking off and then also upgrade your bolts at the same time to a better quality one for the rest of them before they break off but I really really enjoyed having this piece of this gasket material that crosses into that hole to fill up that space and I’m just so so happy with it and I knew you will be too again extremely effective extremely durable just have to be very cautious when you’re installing them not to bend or break or smooshed before you get it on the actual header or in the area where the gasket is placed once it’s in please it bolts up very nicely and actually crushes halfway then you know you’re filling in the holes perfectly so just be attentive when you’re talking everything down…Totally recommend this look for using it again and I’ll be happy to my next exhaust leak to find one and use it again LOL!!!

Great product but fragile. & Be sure to use the correct part for the application. Unfortunately my Ls1 can actually use 4 different sets that have the same bolt pattern. & The application guide is very general so it can be tuff. I even called Remflex & I used the set they suggested. Unfortunately it wasn't what I needed. Then I ordered another set from some four wheel drive place from Amazon only to get a set that was destroyed before in got to me. So I tried 1 last time directly from Amazon & finally got the correct set. Now I'm all sealed up. No more exhaust gaskets.

Used these on an LS7 in a C6Z - aftermarket O-port headers (flange not properly honed/lined up) against the D-port exhaust ports - these gaskets are excellent!!!! I had a minor leak off the bottom side of the exhaust port - removed whatever $hitty gaskets that were installed originally with aftermarket headers, they're thick enough to accommodate some minor fit-up/misalignment issues, excellent line-up with all bolt holes. FINALLY sealed up my header leak, the LS7 sounds absolutely glorious now!!!Will also work with most other LS-based engines with 0-ports - this was a perfect remedy for my D-port issues though!!

Very thick and I like how its kind of like a hard sponge to ensure a tight and proper seal. No leaks so far. Would recommend!

Once again, the best exhaust gaskets money can buy. Sealed up the warped exhaust manifold bolts on my 2005 Chevy 2500HD w/ 6.0 LS engine. Had two broken manifold bolts, so manifold was definitely warped. Extracted broken bolts and installed new with gaskets. Seals great!

By far the best exhaust gaskets on the market, and available on prime! Heck yes

Perfect! Solved my leak issue, and was able to remove the header and reuse one!

Sealed up my leaking turbo headers and have held up very well.
