Best type of inlet manifold gasket?

Yes, another question.

I was looking around on eBay and chanced across an auction for a 2L inlet manifold set. On its own it doesn't interest me, but the gaskets used caught my attention.

I have always used separate metal crush gaskets but the ones they are supplying are a single gasket that spans both ports. I have never actually seen them before.

I need to get new gaskets anyway, so I was wondering which type is preferable?

If both surfaces are machined flat i'd just clean them both with acetone and use Ultra grey silicon. Only a small smere is all thats required, you dont need it oozing into your intake ports. It handles the heat just fine and seals so well you'll have troube getting them apart in some cases.

Good Ian, but Loctite 515 Master gasket instead of dreaded silicone, much easier clean next time without risking putting silicone into your engine (not too much prob on intake ports, but dont start bad habits). Silicone wrecks bearings and blocks oil galleries.

Could not agree more with Matt, good advice there.

Excellent. thanks for the advice. Doing away with the nightmare gaskets entirely sounds like a great plan. I don't know how many of them I have replaced that didn't quite seal right.
