Heads can go on either side- they don't care. And 100% correct- use sealer on the head bolts. I use Locktite thread sealer with teflon, but I've used just about all of the pipe thread sealer stuff from the hardware stores too. Just my opinion, but I don't think that's a good place for RTV type sealers.

Permatex #2 works very well. You will get oil seepage out of the head bolts if you dont

Double ck if you have a temp sender in one of the heads. That one goes on the driver's side. Not a big deal either way, but getting those pipe plugs out can be a pain sometimes.

So it doesn't matter which head goes where...but it can mess you up if you can't get the pipe plug later.

I would also put sealer on the intake bolts, as they can seep oil too.
