Big Block Header bolts/Fasteners?

954 Views 7 Replies 5 Participants Last post by  JeffK
Some of my threads don't look so good on my Brodix RR's. I have the Arp header bolts but I had to clean out the threads and now the bolts are not a completely snug fit. Heads are already on the new block. I looked on summit but can't figure out which ones I need that actually spread like a Poly lock to help tighten the header bolt. Can anyone help me with a part number for this from summit or jegs. Not just regular header bolts. I already have those.

Those look like the ones he is describing. The split lock bolts - Anyone used those yet? I always use the Stage 8 bolts and they are a pain to c-clip.
