Need 1.84" intake valves Chevy

[swampratt]

Things you think will never be hard to get.
1.84" intake valves for a SBC.
Used to be all over the place and now on back order.

I need at least 16 of them.
16 for now to finish the build on my 2 truck engines.
Thinking of turning down some 1.94" valves.

2 sets that were in the heads were over revved by friends and peeled the keeper grooves and I will not use a valve like that.
Do not let idiot friends shift your car.
Do not wait until valve float to shift!
Nearly 8000 rpm with a hydraulic flat tappet.

On a brighter note I had 2 sets of these 601 305 heads surfaced and magnafluxed and no cracks and one set was on this engine and no cracks.

Bent all of the valves from the explosion.
been laying around for 7 years.

I've got an old chebbie head laying down in the barn. Tomorrow I'll take a mic down there and see what the intake valves are...

Thanks.

Nope. 1.70"

But I do have a couple, maybe 3, nice exhaust valves with the optional pressure relief cut in them...

Curious, who do you use for machine work? I used Buddy Rice years ago, but I'm sure it's changed hands since.

I had a friend I went to high school with and raced with that worked at Rice and he told me not to bring my stuff in there.
Some things were fine but crank and rod work and block work forget it.
I did have him grind on a 400 crank and he turned too much off the thrust and I had to get an oversized thrust bearing.
He got me the right bearing.. But a stock one would have really messed up the end play.
Good thing I measured things. I was in my 20's when this happened so that was a couple decades ago.

Folks in Norman does my stuff now. He no longer has that compressor contract so he is back to doing well with hot rod stuff and gets my stuff done quick.

Billy Dixon does some of my head work like surfacing or other things.
I Port my own heads and cut my own seats though.

I had the Cam shop cut down some 1.94" intake valves to 1.84" and I cut the 45° back onto them.
