I'm thinking to prevent for future clearance issues, the shorty headers would be a better option for me.

Thanks for your response and help on this!

No worries, this is why we post, to help each other out

Yes, the bagged Dropmember uses the same geometry as the coilover version, so they would fit with the same magic as mine, probably better, due to the absence of the upper coilover mounts.

For me, shorty headers are are not worth the pain that comes with them (blown gaskets, burnt wires, etc). There are a few nice mid-length options out there that will fit the bill and will not lose too much in translation. Hedman comes to mind with their C10 specific mid-lengths—thick head flanges, heavy gauge tubing, and ball/socket collectors. Uncoated I think are under $300

Out of curiosity, has anyone measured the flange thickness on these headers?

I do not see it listed on the web site.

Also, any idea where they are made?

They are thick. A friend that is with ECR (their corvette racing side) looked at mine yesterday and thought they were actually kooks (high $$$). He was amazed when I told him they were cheap-o chinese specials.

They are 3/8" flanges.

Awesome! Thanks!
