ARP cylinder heads studs often leak. They are a race engine part only. There is no place or need for these
on a street motor. Replace with good head bolts and coat the threads with BLACK Permetex gasket sealer
on the threads and bit under each head of the bolt or washer.

You can remove and reseal the studs but they will likely leak again.
Again the Black Permetex gasket sealer works better for sealing bolts and studs.

the thead cut on the ARP studs is slightly different than the threads in the block.
coolant creeps up the threads.
You are best to not used them at all on a street motor. You don;t need them.

Race engine blocks have blind head bolt holes in the block. That don;t leak coolant
the studs are not a problem on a race block with blind bolt holes. But all too often area big pain on stock blocks.
They are not needed any way.
