Isky Guideplate Install
Hopefully getting my car back on the road (just in time for snow) and just need some tips on setting adjustable guideplates, thanks to @SSlowBoat for gettting em to me

I put them on, get the both rockers centered. Put a few dabs of super glue on them. Remove studs and weld them off the car. Reinstall and repeat

I got lucky I assume with mine. I didn't have to grind anything. Almost all of them needed to be a hair separated or as tight together as they would go for proper rocker alignment at full lift and at the base of cam.
I focused more on mid/full lift more than anything for alignment. Not sure if that was correct or not.
Some of them looked perfect at the base of the cam but as soon as it would go to mid or full lift it was way off. I would compensate to make it better at that position and then finally torque the stud down carefully.
I had to turn the motor by hand several times checking the different positions of each rocker until I was happy. It took a while.Last edited by Badazz 97 TA; 01-04-2016 at 10:17 PM.

The idea of the ISKY's is to allow EACH valve on same cyl to be aligned so it is dead nuts centered L-R on the valve tip. Front to back alignment (intake or exhaust side of motor) is determined by PR length
I did not weld mine once I installed them. Been on for 10 years now
Just put them on and hand tight the RR stud so you can still slide them around but there is some pressure on them. You "may" need to grind off some of the fingers so the 2 sides can come closer together if needed. I had to do that on a few but most were just fine with the 2 halves butted up and a few slightly separated.
They are nice units since the LT1 heads using one piece guide plates you just can "dead nut" line up one valve without effecting the other one
I have 2.02/1.60 valves so for me these were the perfect solution in perfect RR to valve tip geometry96 BBB 383/T56
