I use BPNW for alot the engine parts I use, and they are in your backyard, I find VB to be only offering standard issue parts, no uprated parts, then add to that they offer basicly no tech advice. I like BPNW because they offer uprated choices, like Payen gaskets, King tri metal bearings, Durabond cam bearings, just to name a few, I use APT cams and lifters, not cheap, but the best. Cheap is not the way you want to go with engine parts, you only want to do this job once is my advice.
Here's a biggie for me, the factory used tri metal bearings in your engine originally, so why on earth would you want to only use bi metal bearings in them now, but thats all some vendor offer, BPNW offers a tri metal bearing for your engine in the King line, and it pretty affordable too, so why would not someone want to use that. You'll find in the uprated parts add very little to the overall cost of the parts, but offer much more longer lasting parts. As for Payen gasket set I find they always fit, where the cheap no name gasket sets often times have to be made to fit.
