I know, I know, please not another Speedmaster post.
I moved on to the next person on my winter porting list and as I promised I called before I started on them. I always do this to see if they are ready financially and lay out our plan on what’s getting done. He was gracious enough to say go around him right now as he’s not in a hurry for his Speedmaster heads he had drop shipped here. He was however concerned about what condition they were in just in case warranty issues arose. So to give him peace of mind I agreed to go ahead and strip them down and check guide fit, etc. well I’m on short break after checking out the first head so here we go. I numbered everything on this head and before stripping it down now that I can I did a vacuum test. Even though I will be touching up the 2.02 valve job every port on this head passed with flying colors. Word to the wise. For some reason this head has VERY sharp edges. And I mean everywhere. Chamber, valve cover lip, deck surface. Please be careful. It actually cut the wood on my new Harbor Freight cabinet that I use for all head disassembly and assembly. Valve guides were just a touch on the lose side as always which I’ll take over tight Edelbrock guides. Throwing a Ferrea valve in the guide tightens it up that .0005 real quick. Valve seals on any head I disassemble gets replaced. Shims are 4 on some 6 on others just as before. This head as received after checking spring pressures would work well. The short turn has a little lip that would take maybe 8 minutes per head but now I’m nitpicking.
