Does Comp, Powerhouse have one, perhaps Crane? need one that can clear longer valves too if possible

 

Craftsman 10mm

 

Lol I was just gonna say that.

I got some alum 10mm inner diameter tube and welded a T handle on to get even leverage from the top, works great.

 

I drilled a hole in the end of an old screw driver handle after removing the metal part. Worked like a champ. You can buy them from Summit/Jegs too that I know of. I think their Powerhouse brand.

 

Diamond pistons has the best one I have ever seen. Really top notch!

 

10mm deep socket and small hammer is all you need.

 

i would never use a hammer on a valve seal. a deep socket does work good.
a dab of wd40 on the valve and push her on.
hammer is a no no in my book.
proform has a cheap valve tool, not sure if it will work with an LS1 valve seal. never checked the sizing.
good luck.
