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.

Thanks.

Not sure but I think Speedway Motors has them and a fairly reasonable price also. I think they are made by Percy's.

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.

I've used them, and so far work good.

Thanks. I am ordering now. I guess it won't say big block chevy. I just need the 3/8 by 3/4 inch.

I've used quite of few of those style washers too. We used them in our shop for building paper converting equipment, so I had to grab a few once in a while. They work very well on my header collectors, intake manifold bolts, and suspension bolts.
