04 05 CHEVY MONTE CARLO SS 3.8 V6 SUPERCHARGER HEADER - eBay (item 260755341381 end time Mar-26-11 18:56:47 PDT)

 

I think the general consensus are pacesetter or speed daddy headers. Not sure what brand those ones are. Ive never heard of Speed Starz so I would stay away unless they are just distributing a better named brand.

 

I'd go with speed daddy headers. Pacesetters seem to leak a lot. My SSAC ones are great fitting with minimal leaks but cost a bit more.

 

The picture in the link you gave shows the primaries are 1.5". If that's the case, then those headers aren't even good enough for L36's, let alone L67's. Here's what you should look for for the headers primaries:

L36/l26: 1 5/8"
L67/L32: 1 3/4"
