John -

The part # for the head bolt washers is MD020733, but it should not be necessary to replace them. As another reminder, I would recommend measuring the thickness of each one and use the dimension in the calculation for threaded depth on a particular cylinder. I found a couple of washers on my engine that were slightly thinner than the others - no big deal as long as there's enough clamping range.

Prior to installation, wipe the mating surface on the heads and block with acetone or lacquer thinner to remove ALL traces of oil.

On installation, lightly oil the head bolts - put some 10W-30 in a can and dip the bolt threads, wipe the excess on the rest of the bolt, including under the head - wipe the washers with the oil on your fingers. Torque in the correct clockwise circular pattern (beginning from an inner bolt) and in stages - 30/40/50/60/70/80. If you want the exact starting point for tightning sequence, let me know and I'll email a picture to you.

As a testament to care taken in the head installation - I've put about 3000 miles on my rebuild, but until the past few days it's been a little here and there. I left SC on Friday and am now in Albuquerque - driving about 500 miles/day. The weather across OK/TX/NM has been hot - 98F and I've been pushing it on 32s at 65-75mph regardless of grade. She's used zero oil and the temperature has stayed where it belongs without a hitch (so far). <img src="/forums/images/graemlins/kewl.gif" alt="" />

Good luck,
