Ok so for the longest time I have been trying to figure out how my car made so much power on the dyno... You may not think 600+ hp is that much but on a 2v it's actually a good bit. So I sold my supercharger to open the door for a new project and have been slowly putting it back to stockish to either sell it or go with a new powerplant. I am in the middle of putting back on the good ol' plastic intake mani when I came into a huge problem. Old intake is busted so I had ordered a new one for 99-00 mustang gt since I had done a full pi swap. Intake came in... but it wont fit... and it's nothing like the one that I have on it now. it's wider on the bottom and doesn't allow for the line to go through in the valley of the block. After tons of searching on the internet i'm at a loss. I took it to a mech, and he called to tell me it has cobra/bullitt heads, can this be possible if they are cobra heads wouldn't it be a dohc (side note, i have oil fills on both heads from the head swap) So it's a mystery what the heads really are, which i should know, but don't. How can i tell, and if they are bullitt heads I heard they are worth around $800-900 a piece is that true?

The car has a built block and what I thought were PI heads but now I have no clue what they are... Since I might sell the car I need to know what I've got.. I am wondering if someone made a mistake when i had got the heads a couple years ago..

Pictures. Bullitt heads are nothing crazy. Cobra heads are DOHC. Theres absolutely no way to mistake a DOHC motor for a SOHC and vice versa.

Bullitt heads are stock 2V PI Heads. Any tech that tells you that your car has Cobra/Bullitt heads does not really know much about 2V Mustangs.

Post a pic of your heads, specifically the intake ports.

My bet is who ever you ordered te intake from sent you the wrong intake, off of a 5.4 or something else.

the intake I was sent is a Dorman OE 615-178 which i don't think is a PI intake.. i think it's just a standard 4.6 intake with the upgraded crossover

Yep thats a NON PI intake. The Dorman intakes are junk anyway. Your best bet is find a PI intake on here used, Ive seen a couple lately.
