The rockers are Harland Sharp, but how would I know if they are adjustable or not, and how would I know what specs they are? 1.7? 1.8?

Also, can anyone identify the springs?

Thanks for your help!

The springs appear to be LS6 yellow stock springs . As far as the rockers , You may need to remove 1 and locate the part # to know what exactly they are . As far as the rockers being adjustable , it's not likely as the LS engines use non-adjustable valve trains with the exception that You adjust for cam changes by way of different length p-rods in .025" increments .

Pretty sure they make adjustable roller rockers for these motors.

They do make adjustable rockers as I have some on my LS6; however, these do not appear to be adjustable and they also look like Harland Sharp rockers.

The Harland Sharp's should have a part # on them. About 3 letters and 2 numbers. The numbers will either be 17 for 1.7 ratio or 18 for 1.8 ratio.

Not adjustable. If they were they'd have an adjuster and jam nut above the pushrod cup.
