I just bought a engine. It has a comp cam and comp cam double valve springs. Do i have to remove the inner valve springs when breaking in the engine? What would be the best way to remove them? Thanks

 

yes, you have to. As for how, do you want to do it the cheapest way, the easiest way, or the best way?

 

I think that if you have a roller cam, you don't need to remove the inner springs during break-in. A non-roller, I'd think that you do need too.

 

this man speaks the truth.

 

It has a flat tappet cam. How do i remove the inner valve springs? My dad said to rig up a rubber peice on the end of a air gun and remove the spark plug and pressureize the cylinder so the valve wont fall out. What do you guys think?

 

Yes you need too pressurize the cylinder with air. I used an air hose that is part of a cylinder compression tester kit. It worked well.

 

Works very well!

I have done the same for many spring swaps and valve seal replacements.
