Using later valves in a '39 flathead Just wondering if you can use the later 8BA style valves and guides in the earlier flathead blocks? I have a bunch of valves, but not many guides. Seems the later valve and guides are cheaper than the split-style guides.

Re: Using later valves in a '39 flathead This should pose no problem as long as the complete 8ba assembly is used. I opened up a 38 engine for inspection and it had one 8ba valve and the rest mushrooms.

Re: Using later valves in a '39 flathead You can definitely use the later (8BA type) valves in your 39 block.....just use the matching 8BA valve components with them (springs, spring retainers, keepers, guides). The valve guide retainers (40-6510) are the same either way.

Re: Using later valves in a '39 flathead This is pretty much what all of us do . . . as the split guides tend to move around a bit (between the two) and are harder on valve stems as a result. The best situation is to buy a whole valve assembly "kit" - where you have the valves, guides, retainers, keepers and springs. Mac is a good supplier for these parts - as are others.

Re: Using later valves in a '39 flathead B&S, Corsair is a new poster here on the Barn, I thought we might want to be sure he understands your reference to Mac is Mac VanPlet, NOT Mac's! :)

Re: Using later valves in a '39 flathead Thanks guys for this. I am relatively new here, but somewhat of a regular on the HAMB forum. Thanks for the info, rather new to the flathead, but have worked on a few over the years.

Re: Using later valves in a '39 flathead We use Chevy valves when we rebuild flatheads. They are less costly, and easier to find.
