Cam timing-no specs

Hey. I’m asking if a pair of cans can be dialed in without knowing the cam spec info.

All I know is it’s a Sr20ve 20V pair of camshafts..I hope!

Anyone can help?

Most aftermarket camshafts, especially mildly up-rated ones, are fitted using the standard timing marks, with vernier adjusters being for fine tuning.

Are there any casting, stamped numbers or codes on the camshafts - often aftermarket will have it on the end opposite the sprocket/gear.
