Intake Exhaust Valve Set Fits Buick

[Greg Lib]

Hello,

I am not sure what engine I have, but I bought pistons for 364 1957-1961 and they fit, now I have to buy Intake Exhaust Valve Set but I have a problem finding the dimensions I have. please give me a hint where I can buy it. I have a Riviera from 1965.

In answer to your question:

 

nailhead valves | eBay

 

"Buick rodder" is a  good knowledgable supplier.

 

They can be reached here:

I wouldn't go pulling out the credit card til a bit more research

 

if you have a 364 in a 65 there are some significant modifications to your drivetrain.

 

I am befuddled as to if you dont know what engine you have you would go and buy 364 pistons? Steve

After measuring the pistons, it turned out like that, but now when I check valve 364 there are other sizes.

Most all NailHead valves from '57-'66 have a 1.875" intake valve & a 1.500" exhaust valve with 3/8ths. stems (actually .372" as you have measured) wiith a length of 4.786" with very few exceptions. They are available everywhere, even Napa. 

I agree with Steve. IF you have a 364 there are other problems to overcome.  I'm sure you just measured the bore wrong as a 364 bore is 4.125" & IF it was rebuilt & bored +.030", now 4.155", it would be close to a stock 401 bore of 4.1875".

Those small valves look like nails.

You may be onto something

I have definitely measured well and bought bore + 0.03 and everything is correct and fits, but the company that puts it together needs an Intake Exhaust valve now, and when I check with 364, they have different sizes than those I had installed.  those from the photos
