    Glad to see you are making progress. I found myself in a similar banger situation last year... and wound up machining mine from round bar.

    Cool stuff is never easy... That’s what makes bangers special;)

    MarkF, how close are you to running the engine? It's good to see progress.

    Hi Rick, I've been busy researching and building with gusto. This is the closest I've gotten to on the history front, Joie Ray in what looks very like the car I have.

    Rockers and shafts now machined, remaining work includes drilling the oil galleries etc. Getting there one step at a time.

    Mark.

    Just to clarify a point- the postwar 4 ports used a small cup over the valve spring that the rocker arm made contact with rather than the rocker arm tip bearing directly on the valve stem. This took all the side load off of the valve stem.
    I'm not sure if the Vesco or Butler heads were set up this way or not, but it would be great if someone could confirm this.

    I am piggybacking on this very informative thread about Riley OHV's.
    I am the lucky owner of a 31 Ford roadster fitted with a Riley 4-port head. It was built and raced in vintage groups on the USWC 15 years ago. I've run it as a street car past 5 years, competing in Hot Rod hill climbs and (dirt) drags here in Colorado. The engine is a B-block with pressurized oil; it used twin Winfield cards and a Wico mag.
    I emphasize that I bought the car complete and have only made cosmetic changes and routine servicing-my technical knowledge is limited!!
    Reason for this post. The head gasket has blown; at least I'm hoping that's the extent of the problem. I've stripped off the ancillaries-magneto, fuel and external oil lines; throttle linkage; alternator/pump belt. Plugs are removed and all the head nuts removed in a progressive sequence. All that remains attached to the head is the water pump, which I believe is a V8 pump, and the valve gear. What of this needs to be removed-if any-before the head should lift off? At the moment the head isn't loose, but I haven't applied any pressure yet to lift it before I know what else might be securing it to the block.
    Hoping that this group can advise me.
    Thanks all.

  11. Valve gear needs to be removed. There is a head bolt under it. I would also remove the pump. When it goes back together torque all head bolts then assemble valve train. After first and second warmup run head bolts will need retorqued. Valve train needs to be removed to do this. Big pain in the ass but it needs done. A cast iron head weighs around 80 pounds. I would also remove intake manifold . Can I ask what size Winfields. Good luck.

    I remember this car I was at the starting line at the HRHC. Such rad car!
    62 pan is right.
    Call Steve Serr Miller Hi Speed head and buy a Best gasket and use copper coat and torque 3 times. I have one and I never “lug” it and I learned the torque curve.
    My Winfield’ C’s run best in a box I put them in. Still much to learn about such a simple carb. High elevation is my excuse.
    Brieley makes a cam for this head that will wind past 5k my friend will attest this rpm will loosen the flywheel.




    my excuse

    Thanks for the advice. That job will wait til next week and I'm sure there'll be an update to post here-hopefully a positive one. I cant see any markings on the carbs to confirm the size so I'll measure them when i take the manifold off. Here's photos of them in situ.

    The spare gasket I'll be fitting comes from H Speed, and I'll need couple of spares so be ordering again.
    Thanks for the advice and kind words. Sorry we're missing the HRHC again this year, but the only blessing is that i can take my time repairing the head

    Over the weekend at the RPM Drags I talked to Max Jr from H&H Antique Engine Rebuilding. He acquired all George Butlers Riley Patterns,Heads ( In various in Stages) and parts. He is probably going to sell complete kits next year.
