Proform 66784 Valve Spring Compressor Tool for Screw-In Studs

A awesome tool

Works great

Badass tool

.

Best Tool for Engine IN and OUT of the car

I used this to replace the springs for the SBC350 in my 1973 Nova. It's helpful that the handle pivots so that you can compress the spring from just about any angle. Had to get creative on cylinder 7 as its a tight space with the brake booster/master cylinder. Overall I was able to use this to complete the whole job with the engine still in the car.

Solid and Easy to use

Solid tool but had to bend the fork part slightly to get the best angle. This made changing out the valve springs easy without pulling the heads. The handle rotates which means you can use it in any direction. I used this on a 1973 nova with a 350.

Yes

Work great on my 604 crate

Will get the job done

Changed springs on 602 crate motor. Works decent but does push the spring to one side making retainer clips a little hard to reinstall.

I would buy this product again.

Replaced valve springs on some Windsor Jr heads. The tool works great.

Yes

Cheap and easy to use

The spring compressor I purchased made a tough job enjoyable

I couldn't imagine trying to tackle the job of replacing my valve seals with the heads on the motor and in the car without this tool. I'm sure I'll be lending it out to my buddies.

Works but needed to modify

I had to bend fork flat rather than angle it comes in. The tool does work but i think it would be better on heads with hardened rocker studs. I used this on advanced auto parts stock reman sbc 350 engine. For the price tool works.
