Extrude honing is expensive: Stage 1: $675
Stage 2: $775
Pricing (from their website) is based on one set of V8 Manifolds
Honed manifolds will flow better than stock.
LT headers for these truck/motors are expensive in the short term, but will pay in the long term.
All depends on your goals and end use of the vehicle.
For a hp street driver I'm going to go the stock manifold route. Ive been kicking around a set of headers from JTR they are a hair cheaper than current performance. But 25.00 vs 330 is a good persuader.

Dunno, but installing O2 bungs are a piece of cake though. Buy some bungs from Summit (they're around $5 each), drill a hole where you want it (I prefer a Unibit), and weld them in place (or have somebody do it). Fairly easy and that way you get the bungs where you want them. But it is easier if the headers come with bungs already installed.

I just picked up a set of 2001 Z06 manifolds for my project. The first thing I want to do is try and smooth them up on the inside and help them flow some. I am not sure there are any headers out there for a C3 LS1 swap so this is it for now. What can you tell me about these manifolds?
