What springs are you using in your L98 heads? What are the valve spring diameter? I am looking at purchasing a set of L98 heads, but want to run a cam with .490 lift.

thanks as always:lala: (I like this lala guy)

 

1.25 is the stock diameter it may be hard to get a good set of springs to go .490. i'd machine the spring seats to a larger diameter and get rid of the pull out studs and go with screw in. i'd also trash the factory rotators and buy aftermarket retainers.
