Valve guides Haven’t had an A motor very much apart yet, some must know, were the V8 split guides the same as model A? I have a ton of mushroom stem valves and guides, and 2 motors that may need some. Thanks

Re: Valve guides OK so I will fish a couple out of the loose motor I have & take with tomorrow. My dad is working on one in south Florida, not many resources there.

Here are pictures of the Model "A" & Model "B" valve parts (left) plus the Flathead V8 parts (right). They are not the same.

Re: Valve guides Most people convert over to modern valves and adjustable lifters, available at the suppliers. The two wrench adjustable lifters are easier to adjust.

Re: Valve guides 1941 Flathead 6-cyl. Ford intake valves have been used in A's, they are 1/8" bigger than A valves. '41 was the only year that they had 5/16 stems.

Re: Valve guides There are some John Deere valves that can be machined to fit any model A application. They have 5/16 chrome stems.
The stems will need to be cut off, regrooved and the heads machined to the required diameter. |
Re: Valve guides Bingo! I always wondered about a box of these that I inherited - identical in dimension to Model A/B valves but with a 1/8 inch wider valve head. Per Jim Brierley they are intakes from a 1941 Ford 6-cylinder.
