  Nice Kit!
By on 3/26/2014
I bought these to upgrade a pair of GT40 iron heads used with a Trick Flow cam. The heads were rebuilt and had new seals so I didn't use the included ones. Read the instructions! They state that the exhaust and intake retainers are a different color but mine were not. The intake ones are in a separate marked bag but the exhaust ones are not so you will need to keep them separate. I had to use anywhere from zero to three shims to get the installed height correct. Also, the heads were off my engine which is a lot easier than trying to do this in the car.

Word of advice: If you do this on an assembled engine take precautions to avoid dropping a keeper down the oil drain back holes in the head. They can slide right through those openings!

Yes, I would recommend this item to a friend!

  Good Solid Kit

I have used several of these kits. Nice to have the shims and valve seals in addition to the springs and retainers. If you are planning to run factory E7TE or GT40 heads and want to run a performance cam, this is a good way to go.

This package was an excellent upgrade to my GT40P, B Cam, 1.6 RR build. Valve seals were quality up grades as well. The included valve spring height tool was a nice addition to the package.

Image uploaded by William H. The new Trickflow valve springs fit great and were much stronger than my wore out factory springs. Only issue is the color coordination was not correct. It said one side was black and other was grey but both were black but they are different so pay attention. Great product regardless.
