A T56 is isnt it. I orderd some headman headers from jim pace today. I have been waiting on them for almost 2 months so I can put them in the same time as I drop my zz430 in. The headers are a shorty stlyle. The guy said that in his notes it said the headers were only for a 700r4 or a t350, I told him I was putting a t56 to replace my t5. He talked with his boss and and his boss said it would work because the t56 is smaller. I thought the t56 was bigger but I went ahead and orederd them. What troubles might I have. Why wouldent shorty headers work with any tranny.
