FuzzFace2 Posted April 3, 2020 Share Posted April 3, 2020 The thing on the pics is entirely up to you. But if you have a Dropbox, Google, or Microsoft Onedrive account you can put them there and give me access. And the Dropbox and Google accounts are free. On the pictures I will see what I can do when I have the time. Dave ---- Link to comment Share on other sites More sharing options...

Dave ---- Spent the evening starting to tear down and clean up my "new" heads. Disassembled and degreased. Everything looks pretty good so far. Going to lap the valves, smooth up the chambers and exhaust ports and then paint before reassembly with the new valve springs. These heads appeared to be in better shape than the heads I took off the motor so I am going with them. Link to comment Share on other sites More sharing options...

Brandon/Bruno2 came over to pick up some Windsor heads from me one day a few years ago. I told him where they were upstairs and he came back with the M-block heads. I said "Follow me" and we took them back and laid they beside the Windsor heads. He was stunned. Link to comment Share on other sites More sharing options...

Wow. I'm hoping a little amateur port cleanup will help give me a little more pep. Excited to see if running proper valve springs makes it run any different. I was making solid power before hand. My father once told me his buddy has a set of Modified heads on a Cleveland that were heavily modified. Machined for screw in studs, ported, and the best part was the filled the open chambers with weld, machined them flat and made wedge style chambers out of them. Said it ran like a bat out of hell. Evidently running 400 cranks in 351W blocks was the thing to do back in the day too. Link to comment Share on other sites More sharing options...

Don't know why you'd want to put a 400 crank in something and run Windsor heads. Put the 400 crank in an M-block and bolt on stock heads and you'll have something. Or, port the 2V heads a bit and find a bit more power, esp on the exhaust. Link to comment Share on other sites More sharing options...

Or, port the 2V heads a bit and find a bit more power, esp on the exhaust. The idea was that if you machined the snout down on the 400 crank, bored it .030 over with 302 pistons and use 300-6 rods you'd make a makeshift stroker. They were doing this back in the late 80s when stroker kits for Windsors werent really available yet. According to my dad it was not uncommon to see one of these motors especially with 2v Cleveland heads on them. A guys with the trucks used C9 or D0 Windsoe heads as apparently depending on piston choice they made a little better low RPM grunt. Nowadays aftermarket is light years better so it's pretty much pointless. Link to comment Share on other sites More sharing options...

So I kept looking on ebay and found one. Just “over the hill” from me too, so they got here real quick. Outsides are worn, but look good inside, and a reasonable price.

Got the first of the pair of my "new to me" cylinder heads finished up tonight, minus paint. Degreased the whole thing, cleaned up the intake and exhaust ports (the exhaust side was god awful), cleaned the valves, lapped the valves and seats, installed 288lb @ .580 lift valve springs, and new seals. Pleased with how it turned out. Excited to see how it runs... Link to comment Share on other sites More sharing options...
