Engine Rebuilding... a couple questions

[Thor06]

Hello everyone. As many of you know, I spun a bearing in my purple Talon and I am going to be rebuilding a motor to drop in this spring. Well, I have a couple questons regarding gaskets and bearings.

First off, gaskets. Is a gasket a gasket, or does brand matter? You can get a full no name gasket kit on eBay for like $60, a Topline set from SBR for $160, or a OEM Mitsu kit for $240. Would it really be advantageous to pay twice as much for Topline kit of four times as much for the Mitsu kit?

As for bearings, I am going to go with the Clevite 77 bearings, but on extremepsi they have two kinds, trimetal and aluminum. The mains are trimetal so I am going to get those, but its the rods bearings I was thinking about. They have trimetals for the 7 bolt rod bearings, but they only have aluminums for 6 bolt rod bearings. Are they going to be ok, or should I track down some trimetal rod bearings?

Oh, also what about rings? I got a good deal on some ross pistons, should I get Ross rings, or will any work? Is there any brand that is better than any others? Thanks guys, I appreciate it.
