Flathead head bolt Q?
Hi,
I'm replacing the head gasket on a '37 L-37 257 ci flathead Eight. Some of the bolts are a little weak from rust near the threads, so I'm going to replace them all. Does this require special bolts?, or can I use standard grade 8 bolts? They are 7/16" by about 3 inches long.
Thanks, Jerry

After I reamed the rust & crap out of the passages, the new bolts are a much better fit, tighter, but not too tight to bind.
