The Stovebolt Site Forums The Shop Area Engine Shop 235 rebuild - what valve springs to use

Try Federal Mogul/Sealed Power VS424 for 235 hydraulic cam engines and 261 engines.

Try VS534 for 235 Stock solid cam engines.

I do remember finding comparable valve springs in my Comp Cams catalog. Buick 455 maybe?

Here's a link to 235/261 engine specs.
