Hope you get to working on your truck soon!

Remflex's description of the 7002 says "for header applications." I asked them at the time if I wanted the 7002 or 7010 and never heard a response, so I just went with the 7002. The 7002 says it has "EGR Gaskets" included but I think they are talking about external piping for carb applications, not the manifold gasket (clearly.) It is a little misleading.

I noticed during this swap that the shop that assembled this stuff used 4 bolts and 4 studs on the exhaust, rather than 8 studs. With the Remflex it did not matter, it only gets torqued to 20 ft/lbs. But, with the "normal" gasket, I was a bit scared to torque up to 35 ft/lbs. I don't think you can tighten that far into aluminum although I could be wrong. I did not want to risk it. So, there is a slight leak at the flange that maybe would be gone at 35 ft/lbs, i don't even notice it with the radio on. But I will order up some toyota studs when I get the 7010 gasket. Another benefit of the remflex is that it is a thicker gasket, easily double a stock gasket, so if you cut out the unnecessary gasket material between the exhaust and EGR ports, you will be making an even larger channel for the EGR flow.

I plan on using a lock washer and standard nut instead of the crimped self-locking nuts.
