Great value for the money. Installed on 243 heads with no issues.
These are not OEM GM rocker arms, but they feel and look nearly identical, no issues in the casting whatsoever that I can see.These are insurance so if you have a rocker fail the needle bearings don't scatter into your motor like the factory rocker arms will.

Good quality but, shipping was a joke.
Michigan Motorsports makes products and USA owen and came a week before it said it would. I have bought many products but, I'm highly disappointed in shipping on these trunions they came in a bubble wrapped lined envelope what a joke. Box was beat to crap and crushed In luckily nothing was hurt. Quality is great just shipping on these is a joke. I don't mind paying more for shipping for better quality. Just do better already talked to their customer service they are great.

great parts zero issues, new engine build with big cam 450+ seat pressure and these give me no complaints. bolt on and go. recommend moly lube for initial start up for good break in and metallurgy process.
