Not Ranked
Mike, not only am I using a block with a 9.5" deck but yes, the heads do have raised ports and a wider bolt pattern vs. the 'stock' Superformance headers. I've spoken with a few shops and they would rather just start from scratch rather than to try to re-work the old headers.
Tube size is not a real problem, but the height of the block and ports are... The geometry of the headers has changed vs. 'stock'.
Thanks
