Should I keep these heads?

On a 95 degree day at sea level (Sacramento, CA) it ran a best of 13.35 @ 102 mph, with a best 60-foot of 1.91. I had to leave at 1,200 rpm... no bite. Driver wt. 250... :angry7:

They don't call it the Sacramento Slickway for nothing!

As far as compression goes, I wouldn't go over 10:1 for pump gas with the iron heads. Not sure what you can get in Washington, but with our 91 octane in CA 10:1 is definitely the top end.
