I am currently running a 91 302 roller block, E303 cam, Edelbrock 600 cfm carb, MSD billet dist, Edelbrock Performer RPM intake, T-5 trans with old style (z-bar) linkage and sending the exhausts out through Tri-y headers, H pipe and Hooker AeroChamber mufflers. I have a leak in the Tri-ys and am looking into the Hedman Elite Shortie headers model #88308 for $259 from Jegs. I am wondering if anyone has used these headers with the same set up that I have and had any issues with fitment. In particluar with the trans linkage, clearance. Thanks.
