Made sure all the intake valves have the new seals I bought from British Car Specialists plus the new set of springs I already had for the valves. The two mating surfaces were cleaned with a white (finest grit) Roloc brush. I have the correct head gasket (copper faced). Tonight was the night to torque the head down to the block. My surprise, for some stupid reason I only ordered 8 new head nuts. I managed to order the correct amount of washer for the head. No idea what my pea brain was thinking. Also found out the head nuts are Whitworth (3/8") size. I have a Whitworth socket set, so tragedy averted there. I seem to remember someone talking about the water jacket blanking plate earlier this week. That made me look at the front of my block. Three studs and an empty hole. No cover. I managed to find two blanking covers in my stash of parts and a gasket in my gasket set. Woohoo, but no nuts or lock washers. Can someone tell me if these little nuts that I do not have are Whitworth nuts. If so, what size? I have a generator bracket, but there are no threaded studs for the block or nuts to mount it with. Once again, Whitworth? The closer I get to putting this together the more stuff I find out I don't have.</span><o:p></o:p></p></div><div><p><span lang=EN-AU>Mike MacLean</span><o:p></o:p></p></div></div><p style='margin-bottom:12.0pt'><span lang=EN-AU>_______________________________________________<br>Support Team.Net <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>Suggested annual donation $12.75<br><br>Archive: <a href="http://www.team.net/pipermail/healeys" target="_blank">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive</a><br><br><a href="mailto:Healeys@autox.team.net" target="_blank">Healeys@autox.team.net</a><br><a href="http://autox.team.net/mailman/listinfo/healeys" target="_blank">http://autox.team.net/mailman/listinfo/healeys</a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/healeydoc@gmail.com" target="_blank">http://autox.team.net/mailman/options/healeys/healeydoc@gmail.com</a></span><o:p></o:p></p></div></blockquote></div><div id="m_6037447791772944075x_m_2173325284267159273x_DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><p><span lang=EN-AU> </span><o:p></o:p></p><table class=MsoNormalTable border=1 cellspacing=3 cellpadding=0 style='border:none;border-top:solid #D3D4DE 1.0pt'><tr><td width=55 style='width:41.25pt;border:none;padding:9.75pt .75pt .75pt .75pt'><p><a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" target="_blank"><span style='border:solid windowtext 1.0pt;padding:0cm;text-decoration:none'><img border=0 width=46 height=29 style='width:.4791in;height:.3055in' id="m_6037447791772944075x_m_2173325284267159273x__x005f_x0000_i1025" src="cid:image001.jpg@01D61A21.0E21D6F0" alt="Image removed by sender."></span></a><o:p></o:p></p></td><td width=470 style='width:352.5pt;border:none;padding:9.0pt .75pt .75pt .75pt'><p style='line-height:13.5pt'><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:#41424E'>Virus-free. <a href="https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient" target="_blank"><span style='color:#4453EA'>www.avast.com</span></a> </span><o:p></o:p></p></td></tr></table><p><span style='color:white'> </span><o:p></o:p></p></div></div></div></div><p class=MsoNormal style='margin-bottom:12.0pt'>_______________________________________________<br>Support Team.Net <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>Suggested annual donation $12.75<br><br>Archive: <a href="http://www.team.net/pipermail/healeys" target="_blank">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive</a><br><br><a href="mailto:Healeys@autox.team.net" target="_blank">Healeys@autox.team.net</a><br><a href="http://autox.team.net/mailman/listinfo/healeys" target="_blank">http://autox.team.net/mailman/listinfo/healeys</a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/eyera3000@gmail.com" target="_blank">http://autox.team.net/mailman/options/healeys/eyera3000@gmail.com</a><o:p></o:p></p></blockquote></div></div></div></blockquote></div></div></body></html>
