G92, LB9 305 TPI, 3.23, Bright Red with Carmine Interior, Pioneer DEHP47DH CD deck.2 JBL DS645 4*6 (F).. 2 JBL DS965 6*9 (S).. New 305CI TPI ,World Torquer Heads, and soon to be Body Work

 

From my experience it would have to be www.competitionproducts.com Under $600 shipped.

Shoot Shoot!!!!!

 

That's the conclusion I came to after my research. Beefy's price is unassembled, though. I upgraded springs and retainers, so was around $625 unassembled and shipped. Assembly adds about $50.

They do benefit greatly from bowl work (at least seeing how they come and the fact that the magazines pocket port them before testing them, and World themselves recommended bowl work to me). I went ahead and did the gasket matching and polishing per Standard Abrasives guidelines (which World indorsed but didn't say were necessary - just bowl work).

Not sure how much they would be assembled with pocket porting. I didn't ask, not even sure if they offer it. I had always figured I'd do it myself, even though it was my first journey down that path. The Deluxe Porting Kit was another $35.
