OTC4572 Large Valve Spring Compressor, black

Q: Valve Train checking spring

Tool is not for checking spring. It's for getting spring off of the valve stem. With the head off of the motor.

Q: Does this tool come with a case? Thanks.

My tool did not come with a case.

Q: Does anyone know or have you used this on Harley big twinn heads, will it work?

As long as the valve is larger than the compression adapter, it should work

Q: Can I use on 65 Pontiac big block 389 cu.in. Heads

I can't say for sure, but I've used it on Small Block Chevy, 16 valve Honda, and 32 valve Modular Ford engines. It works great.
