I have the bbks on my '93 in my sig which are very similar to the mac's in design. I don't really care for them and will likely opt for pacesetter LTs later on down the road. fitment seems to be fine, plug access isn't very good (comparable to SLP's), and case in point, even though they are not very big headers, you still need to pull the ypipe to remove the starter, so if you have one of unknown origin or life, you may want to go ahead and replace while you've got good access. The ypipe flange I wasn't real please with as I prefer crush sleeves to flat flanges, but regardless, I doubt I'd have a ypipe coated as they are far enough away from the block to not be that big of an issue, IMO.

I think the wires will fit up just fine, just ensure you either use heat shields per wire, or tie them away from the primaries. Good luck.

 

The plug access w/the Mac,s are one of the best from what i,ve heard,and i,m getting the y coated w/the headers as it,s a lot worse than the headers themselves.I only want to do this once!
