Default TPI gaskets

I have a question about runner/plenum-runner/manifold gaskets on the L98. I see aftermarket intakes with bigger ports and bigger diameter runners but I can't find gaskets made for these larger diameter pieces. I prefer to use Fel-Pro and they do not list anything other than the stock configuration gaskets. Is there another company who sells gaskets to match the aftermarket pieces or do these gaskets only come from the manufacturer of the aftermarket pieces? I am presently porting a stock setup and even tho you can't increase the port size very much the Fel-Pro gaskets are still smaller than the opened up ports.

Here a set from TPIS, but I believe you can also get them from Jegs or Summit

RTV...i prefer permatex ultra grey, seals great, color matches the alum...use a wood-cutting blade from a sabre saw as a squeegee to get uniform thickness, let stand 20 min-1/2 hour before assy to let the RTV ''set'' (too soon and it will leak)

Mr. Gasket makes an oversize runner gasket set and they are cheaper than the other aftermarket gasket sets. Any speed shop can order them for you. I've used them and they work great.
