Heads I'm getting ready to take the jump into a set of heads and a cam, and I figured I'd pick my heads and then pick a cam to match. I figure my options are
AFR 205's (298 CFM at .600lift) and 2.020 intake and 1.600 exhaust ($2300).
Trick flow 215's 80cc exhaust runners, 64cc combustion chambers, 2.04" intake valves, 1.575" exhaust valves, bronze valves (320CFM at .600 lift) $2400.
Patriot Stage three 5.3 heads (2.055 intake 1.6 exhaust 320 cfm at .600) $1,400.
Patriot Stage three ls6 style heads (2.08 intake 1.6 exhaust 322 cfm at .600) $1300.
Dart 205 (2.02 intake 1.6 exhaust 296 cfm at .550 lift) $1850
I've also been told that a 225 is too big for a stock displacement street car...any truth in this?

if you have the $$$...go for the TFS 215s...they are showing some insane numbers!
225s with a decent sized cam is not to big for a street 347 motor. you may get more low end with the smaller runner heads, but it would still be very streetable
