I got all my 235/261 gaskets from Ebay.
The brand is ROL and it is a complete engine set with everything but a rear seal.
We did several engines with the kit - no problems.
The seller is
http://www.oldtimeparts.com/ The whole set is $39
It comes with a 2 piece intake/exhaust sandwich gasket that is a metall layer with a waffle pattern on one side and a common header gasket material layer on the other side. Verry thick so it even sealed great on 2 engines with wraped headers.I always use copper spray - but that`s a religious question.
