I'm getting ready for my proposed engine swap. The new motor has 2V heads. I now have 4V heads. Question, Will my current headers fit the 2V heads?

Bill,
If the heads have a "2" cast into the upper corners, similar to the "4" cast into the heads of the 4V motor, then the answer is NO, there is not enough exhaust port "flange" to mate up with the large 4V header flanges. The "2" cast into the head indicates it is a US 2V head.
The Australian 302C head, which was such a popular replacement head for many years, has no "2" cast into the corners. The Aussie head has a larger "flange" area around the exhaust port, it will seal up with the 4V headers just fine.

OK George, If i put the 2V motor in. Where do I get headers?
Hey Bill....
I'm not all-knowing when it comes to what each vendor sells. I have seen Larry Stock advertise 2V headers (Pantera Parts Connection, Nevada). Hedman used to sell 2V Pantera headers. Somebody may still have them in stock. You may want to start with your favorite vendor & go from there.

LPB, if you are gonna run twin turboes you will wind up fabricating your own anyway.

I've got a set of low mileage Larry Stock 2V Hedman headers I'll sell. I won't have them available until the first week of June though.
