Holley put their stainless steel long tube 1 3/4" primary LS swap headers on clearance and dropped the price by over $500, so we pulled the trigger. 1 3/4" primary should work well enough with the engine as it's currently set up. Mid length headers would have been smarter from a ground clearance standpoint, but these are supposed to tuck up nicely when used with the Holley engine swap mounts. We'll see this weekend.
