Super fast delivery!

Your Fel Pro and of course good quality. Not installed yet but poorly updated when I run into problems but I don't expect anything either. Delivery was great, super fast. Arrived 2 days early.

  • GOLS certified
Cons
  • Something different

Wrong screw set in box

It took a little longer to get here but thanks to Michael. My issue with the one set I received is that the two shorter screws that come with the set are too short and don't work (by about 1/2).

Pros
  • High marks for grip and durability from testers
Cons
  • Bad impression

They fit perfectly and work just as well as factory bolts

I needed new bolts for my 2000 Chevy 4.3 Blazer. I bought them here on amazon.com. I just placed an order and they arrived in a few days. .They fit perfectly and work just as well as factory screws. If you remove the cylinder head on this type of engine, the bolts will need to be replaced. They were so easy to get here on amazon.com that I just searched for the keyword, pointed to it, clicked and checked, just sitting here. Thanks amazon.com!

Pros
  • Sturdy construction
Cons
  • Durability

Does not apply to "Z " engines. The boxing side agrees.

Wherever I look for a Fel Pro Cylinder Head Bolt Kit, the Fel-Pro Cylinder Head Bolt Kit part number ES 74034 fits a 1987 4.3 "Z" engine. In my experience, the part number does NOT match 4.3 "Z" engines. I converted the engine from a 91 C1500 with the "Z" engine that was installed in my 1987 Astro. I think this is a bad part number from the manufacturer NOT Revain or any other supplier as they all have the same set of head bolts. If you look at my photos you can see the difference between the…

Pros
  • Great Design
Cons
  • Crumpled Packaging
