What is your cruising speed to work?
At what rpm are you steadily moving at?

Rob,

Route to work is 50% city 50% highway. 40mph city and 60/65 mph highway.

Went from 2.76 open 7 1/4 to 3.55 8 3/4 still runnin 14 inch 60 series tire. need to install new speedo gear...no tach but I'd guess based on sound it bout 2700 or so highway.

sounds like you and abodybomber are in agreement...keep the stockheads...get some bowl work and 360 valves. I'm no engine builder so any additional details would be greatly appreciated. What exactly should I ask for at the machine shop and roughly how much should I expect to pay...assuming all new valves etc....thx you guys are awesome
