Bassani shorty headers/Have too relocate dip-stick??

I have Mac Equal Lengths (similar to your bassani but the bassani is better built).

Spark plugs are a bit harder to change over stock but not that hard.

The headers were on there when I bought the car but I think the dipstick is on the 4th bolt from the front of the car if that is any different than stock????
 
Spent about 40mins last night trying to get my stupid dipstick back in with my longtubes. Ended up having to gently bend it straight, get it in, and then bend it back. I was very lucky the stupid thing didn't break. I'm not sure what brand the headers are, but thats one experience of dipstick issues.
