Not a lot of options when I was thinking of a change. So I am running 42 DCOE 8 Webers. However they do not work well on a stock engine.
So it has to be breathed on. I did all of this in the mid 80s, Isky cam,header, milled head .090 which gives you 10to1 compression. 87mm pistons.
With the head milled at .090 or more you have to run a steel shim Head Gskt. Now they have a solid copper Gskt. The car was amazing to drive
fast!!!! Now I'm older more $ less brains and a lot of go fast parts in my garage waiting to be installed. photo of my cyl. head at .127....

Have a great Day TMG

FYI,
The solid copper gaskets are very sensitive to liner protrusion. You need to have it very accurate or you make milkshakes in the crankcase.
That copper does not compress, at all.
Stick with the shim steel or cometic. For those running 89mm bores, you can call Cometic and order a TR4 gasket with 92mm fire rings. They don't advertise them on the website.
Part # H-0793-SP-4043-F at .043" thick. Shim steels are fine, just use a couple good coats of aerosol copper coat. They also work for the 89's.

They do with the rubber boot adapters, just like MC's. Not that you have to with Mikunis but when i had to take carbs off for other work I could get one off in about one minute, start to finish. One manifold hose clamp, one fuel line clamp and one screw for the throttle linkage & done.
