does anyone know where to buy a valve compression tool for a dodge 4.7

i am trying to replace my head gasket and napa auto parts and autozone carry it

 

Harbor Freight tools.

 

I just did this about 6 months ago. Advance auto, buy the compression tool and return it when your done. I think they give you up to three months to return it. I've found that advance auto does the same thing but got a quality valve compressor at Advance.
