Hi,
I should know this but I want to be sure. I have a pair of 71 351c 4v exhaust manifolds laying around and I'm throwing them on ebay. Will these fit all 4v's from 70-73?
Thanks
They will fit both 2v and 4v heads... however will not perform on the 2v... it would be a waste. Had them and tried them on a '73 cleaveland that I had...no dice... thats y the give them different designations
