Twin cam head conversion nearly done

PostPost by: gsminors » Fri Feb 15, 2008 12:37 am

Made some progress on the webber head this week. I have all the valves dialed in with correct clearences, this took some time to do from scratch. I am sure glad I have my fully equiped machine shop to do this. So what I have now is a fully rebuilt head with new valve guides, polished valves, polished ports and chambers, head thickness is 4.635". New cam bearings, the cams have two grooves so I presume they are the sprint cams. Just waiting for a new water pump from Dave Bean this turns out to be a upgraded one which took three pumps before I got the correct one sorted. I hope to have the head back on this month. I have attached pic to show progress. The other thing I might do is to make a set of light weight pulleys. So it goes on and on. Need to get it ready for Spring.
