So I'm using the patriot headers and a moroso oil pan which plants the hole for the dipstick right behind them where there's not a straight shot at it. The pan fits the stock diameter size of the dipsticks.
What I have at the moment is from a small block Van, one that points towards the front of the engine instead of straight up like a truck/car. It fits, clears the headers and all, but of course does not read accuratly and
has the added fun of a built in game of Operation where if you're not careful the stick will arc to the positive battery terminal when you slide it out.

So lend me your suggestions!

Lokar makes a few options that are flexible with a flexible outer tube that can help while also looking nice. They also have ones with a locking feature so you can rest assured that the dipstick stays put I have one and I like it a lot
