Now that the Hemi is in and the headers on you now know what works and what dont. Would like to know if it would have been easier installing with the heads off? I need to install a 572 Hemi into an A body using TTI 2 1/8 headers. My thought was to install with 727 bolted on, but without the heads. Really not sure of the best way to do this, but any opinions from you would be appreciated. Thanks
