Scotty,
I have been reading the BBF forum for about 1.5 years. I must say that there is a tremendous amount of information that is put forth by experts. I thank you. I bought a '87 Mustang w/ a 545 by CHP. The engine has Probe flats with -3cc tops, Crane solid w/ .621 lift with 292 duration and 72 overlap degrees @.020. RPM range is 4200 to 7200. Stall is 4000rpm. The heads are Dove with light polish and 2.25 and 1.76 valves. BG 850 carb on a Stealth. Gears are 3.27( a little high). Exhaust is Hooker Comp with 2" tubes and 3.5" collector, exhaust pipes and mufflers.
I would like to stay with the above combination except add alum heads and some new ceramic headers. My present compression is 13.3:1 however I would like to reduce it to 11.5 to 12.5. Can I use the Street heads to get the chamber volume increased to mid 80's to low90's. Or what other options are available?
Thank you for your help.
Mike
