The design goal was 1600hp Pump Gas.

Rockers are next on the list...

Unfortunately I am serious, even with that much material removed from the rockers quite a few of them have marks which indicate they are still making contact with the springs/retainers.

The pushrods are Manley 25374-16 9.750 length, 3/8 diameter, .120 wall.

Take another look at the original balancer picture above. Those metal shavings were packed in behind the balancer bolt.

I thought those looked like metal shaving but was waiting for someone else to say it. LOL - Good luck, at least your finding the problems now and not on the track.

Take a look at the picture -- If those are Manley springs the end with the champher should be up - -unlike yours - that would contribute to your spring retainer issue - although prob will not fix it --and Id say goodby to those rockers --

Based on the list of part numbers Lynn sent, the currently installed springs should be Manley Nextek 221424-16.

Dual, 1.640 in. Outside Diameter, 647 lbs./in. Rate, 1.070 in. Coil Bind Height
"[email protected] lift , [email protected] lift

The rockers will be going away to hopefully live a long productive life inside a basically stock engine. They will be sold to help finance rocker shafts and additional required machine work. Watch for them in the "Other Pontiac Parts for Sale section".

The 2 spare valve springs I have pictured below don't have chamfers on either end.

Ed,

What are you doing about rocker shafts? I need to build a set for one of my engine builds.

Hi Calvin,

After cleaning up some chit, I was going to send them to Crower and have a stainless steel set made. The rocker stud locations have been moved on my RA-Vs. Are you making your own?
