I bought a set of arp head bollts for my 428 from summit. They were in a small box so I put the heads on after putting on new head gaskets torqued them down and that is about all I did that day
. I jump back on the engine the next day and in another box I find black washers that look like they fit the head bolts. I have never put washers on any head bolt before but I am thinking maybe I made a mistake not installing the washers.
Question is do I remove the bolts and install washers and do I need to put new head gaskets on as well or just do one bolt at a time
Also torque arp said 100 pounds and pontiac says 80 pounds which is correct.
This install is going real slow. First I wait a week for new motor mounts then out of town for two weeks. Then the water pump is too long so wait 1 week to get the correct one from Ames then out of town for 12 days.

Then I put the crank and water pump pulleys on and they are touching.
Ordered a smaller crank pulley as old one is hittting the frame and it is time for me to go out of town as soon as I get it.
