It's just a HR OEM mani (no porting). If you boost a VHR mani on this motor what's it gonna hurt to do it to a HR mani? Don't we boost HR's as well? Yes we do. With that mounting plate for 4 out of the 8 bolts that hold that mani on, it'll be just fine if not better than the OEM bolts pushing on the inserted metal sleeves because the load is so spread out. You'll be fine.
