Did have to grind a little (3/8) off pass side frame . Also ear on transmission and nub on block above oil filter. I used MSD multi angle plug wires.

Thanks for the feedback. Yeah, they might be the only game in town for a direct fit 1-7/8 LT header. I think there are some others that *might* or *should* fit (keep hearing trailblazer SS should) but they aren't sold for our specific application so I'm staying away (I don't want to create unnecessary headaches). My engine guy compared them (visually) to his engine dyno headers and he said they looked pretty close.
I haven't heard anyone grinding on anything but the transmission to fit (and figure since mine is a M6 I might not have to). Guess I'll brace myself in case I have to do some more "fitting" like you did and maybe leave the front clip off until I know for sure.
