Trying to figure out what valve spring are on a set of 500 hp heads they were refreshed with only 10 hrs on them the springs have a orange paint line on each one,, any one have a clue who may use this paint on valve springs.

I have Comp Cams they are on my 500 HPs thay have the same orange line(new)

they

I have a set of comp 929's and they have the orange stripe.

tHANKS ARE THEY A GOOD SPRING.

929's are an excellent series !

Comp 929's are a very good choice for a 500hp replacement spring.
