If you buy a set of Felpro intake/head gaskets they come with a little cut out for blocking (well the 1250 does anyway).

Re: blocking off holes in heads

if you are talking about a big threaded hole at the end of the head, Trickflow make a plug that screws in and also has an internal thread so you can still use the hole for accessaries like alternator or p/s.
