comp 910 question.

Update. Got them installed and the lower seat isn't correct they don't fit at all. I reused the stock seat and put a .015 shim in it to make the stock seat the same height as the comp cams one.

is that using the part numbers DieselBoy posted?
memory fuzzy here on nomenclature...stock seats are the seal as well so the seals remain stock in the beehives?

There are two types of springs in both pictures above. The 910's and the beehive springs.

Why don't you post some pictures of your springs to help us diagnose.

the motor and parts are at the shop 10 miles away..my springs, head and keepers are identical to the 3 springs on the left...now i need to decide if i want to use them or get 910's;;if i use them i need some spec's to install them...

You need to get yourself a valve spring micrometer and check the installed height. Once you get your installed height, compare that number to the spring's pressure at that height.

There are two different valve spring micrometers: one for regular springs and one for beehives.

here is what i have...stock spring on the right.. do you by chance know what mic i need??

You can use that mic but it's made for regular size springs. The retainer is made to sit on top. The beehive retainer will "fall" in. You need to measure the top lip and add it to the installed height.
