Hi, i'm back here with a new name, I had to change my name which was bertrandboss, my mailbox having been hacked !
I still own my 1966 Buick riviera GS, the engine of which was changed by one of the previous owners, for a 401 nailhead (MR code).
The cylinder heads are being completely refurbished, and I need information about the height of the valve springs.
I know that the height is measured with a special micrometer to determine the height of the springs, as well as the thickness of the shims intended to adjust this height.
I need several informations : 1 ° Is there an average height of the springs which must be respected, or are there other parameters to take into account to adjust the height ?
2 ° What is the procedure for measuring the height with a micrometer, and to determine the thickness of the shims, (how to use the micometer) ?
3 ° Where can I buy single shims , (I only found them sold in lots)
4 ° I looked for a micrometer on the web, I saw that there are different models compared to the measurements they allow to perform : 1.600-2.200 Height range or .600-.950 height range, etc.
What model / what heigght range do i need ?
Thank you for your help.
