Default L98 OBX Header owners step inside

Guys --

Installing OBX headers on my L98. Just the other day I noticed the passenger side has been dimpled to make installation easier. The drivers side has not, however. Is your drivers side punched in to allow the bolts to go in easier? I'm thinking this was an oversight by OBX, at least on mine.

Oversight or NOT - "you've got what you've got" and you're left to use them. What other options do you have? I would think - NONE!

Since you've not installed these yet I'd suggest you fit them to a cylinder head "on the bench" first. If you need to borrow one then borrow one. There should be many around I would think that would offer up a cylinder head for use. If you've had machine work done in a shop, ask them.

It's a wise move if you can to do a fit prior to the attempt at the install regardless of brand. There can be issues with "ALL"!

They're in the car. Passenger side all bolted up, no issues. Driver side bolted up minus two bolts. If the heads were still off the engine, then I'd do as you suggest..

Anybody actually have these headers?
