Are Ajusa gaskets any good?

See what people across the web are saying about Ajusa

I used an Ajusa head gasket, well, complete gasket kit on my s54 rebuild, nothing but good quality, good enough for 1000hp supra engines so I think it will be ok for an s54! The full gasket kit they do had all the gaskets, all equally comparable to the gaskets that were removed, all fitted perfectly, can’t fault it.

On the +2 i went through a bit of a spate of head gaskets, for some reason the copper type one wouldn't fully seal so i went with a Ajusa gasket (from Burton Ford) which has been fine ever since....... the 2 seater has a Felpro again from Burton but i believe they only come in stock bore sizes.

I have used a few Cometic gaskets on YB engines before now and they have performed outstandingly well but as your aware they would be massive overkill on a Twincam. I had some issues with the Cometic cam cover gasket (twin cam) as they have no tolerance for warpage.

My experience was exactly the same as Grizzly - copper didn't work (twice) and I have since used Ajusa with zero issues. Would not go past them now
