Hi guys, I have another question and I couldn't find an answer to it on here or on Google even.

I am going to be doing the 1.6 roller rocker installation this month and I was going to upgrade my valve springs along with these. I have been trying to find a set that will go with the Proform's I have now.

Does anyone have a place that sells springs for this exact product? I looked on Proform's website but there isn't anything with springs on it. I know I can look on Summit but I'm too sure about which brand or specs I should look for.

Any help is appreciated. Thanks!

 

It all depends on the cam you have in the car or the one you will be puting in. Go with the springs that your cam manufacture says to, now as far as spring diameter goes. Proform part #66908 is good for max OD 1.400 part #66915 max OD 1.500 both are for 3/8 stud. If you go to a bigger valve spring and the heads are stock you will have to take them to a machine shop to have the pockets cut for the new springs last time I had it done it cost about $40.
