Replace head bolts?

[Seattle Sam]

Hey Darren,
I believe you can re-use those bolts if you want to. Just clean em up good with a wire wheel, and run a thread chaser (or a tap)into the threaded holes in the block to make sure they are clean. Don't forget to put RTV on the threads to keep coolant out of your oil!

If you want to look original from the outside but have that warm secure feeling that comes from using the best, buy the ARP fasteners and use them in all the locations under the valve cover, then re-use the originals for the row of bolts outside the valve cover.

You could try contacting Rick's first gen or maybe SCW to see if they have a source for new bolts with the correct markings..
