[Fot] spitfire woes

[fpspitfire at comcast.net]

I've seen valve float on the dyno.  Looks pretty much like what you descibe Dayle.

Pulls well until it hits a magic number, then all hell breaks loose.

Easy to check.  Pull a couple valve springs and check them...if you are a place with a chassis dyno, there should be a valve spring checker near by.

Back to back with a new set found about 40 lb difference.

Also, beware that I've found Isky has quit selling the good spring sets for the Spits.  We are trying to find a suitable alternative, but haven't come up with anything yet.
