Who has them?

Or, what valve can be made to fit?

TIA

Si lists the 1.70/ 1.44 valves in their catalog.

If I ever do another slant I plan to see what they have in Mopar cam lobe profiles.

But back on valves, using Chevy or Ford valves gets you to smaller diameter valve stems.
I have Ford 289 valves / beehive springs in the slant in the 68 Barracuda

John if you are using the smaller stem valves, then you need to have the guides replaced and resized to match correct?

Greg, that's a relatively easy task. You yourself can buy K-line bronze valve guide liner kits from Goodson and other companies that sell automotive tooling and install them with basic hand tools you probably already have. You still may need a shop to hone the guides for you unless you want to purchase the honing mandrel and other accessories as well. Going to 5/16" stems or even to 7MM from the stock Slant stem size really opens up valve selection and tremendous airflow improvements over the stock valves.

I like the Idea, I just have no Idea on what parts to buy or how to proceed to do that as I have never repaced any seats or guides in a head.

I can only guess what might be......
I would guess Sodium Filled, Inconel, Helium infused Ford Stuff.
And in a sectioned, welded, epoxy ported super duper head.

And all I have is some 20 year old "Street Motor"
Oh how can I have any chance.....

Mokan in April???
