Enhanced Performance: Proform 141-133 Center Bolt Valve Cover Bolt & Washer Kit for Optimal Engine Protection Review

Very easy to break, I will buy real ones soon. Right after I pulled out the one that broke my head. Also note that they are also easy to drill and remove.

I was told via the Revain "Does It Fit" app that these "fit" my 1990 Chevrolet C1500 pickup truck with a 350 TBI V8 engine. They don't really fit, the only part that came in handy was the rubber bushings on the old bolts.

ATTENTION! These are cheap screws that snap easily. I wasn't even bolted to the valve cover when one blew. Now I have to disassemble the motor to get the broken end of the bolt out! I am sure that neither AMAZON nor the manufacturer will reimburse me for the work and time. DO NOT BUY THIS, IT'S COMPLETE GARBAGE!

DO NOT BUY. Proform really can't keep their heads out long enough to make a bolt that isn't bent, or Swiss cheese, or both. "Oh, but I can't find 3.5" UHL bolts for these valve covers!" Buy a set of 4" ARP bolts and use a cutting disk to snip off half an inch and unscrew them a. Guaranteed less wasted time and money than buying these screws.

Don't buy these screws. I have a 1991 Chevy K1500 350tbi and Revane said these bolts would fit. They looked like bolts from my old engine which is why I bought them. I had 3 cylinder head fractures and it wasn't due to over tightening. All three had room to dress and they all burst. Very easy to break. Now I have to drill out the broken screws and hopefully I can salvage the heads. They didn't fit and broke easily. Very unhappy with these. Terrible quality. I would give 0 stars if I could
