Thanks Mike.
I am actually going with a cam that is designed for use with stock springs. I just know where to find these, and don't know if I'll be able to locate stock L6 springs.
I appreciate you going back to your source and re-verifying.
I am building a F54/P90 engine for my 72 240z.
I have a line on new-old-stock valve springs for a 2000 raodster.
I recall being told (years ago) that these could be used in a Zcar.
Can anyone confirm this (with authority)?
Thanks,
Rick
