Thanks for all of your comments guys; all very helpful.

I thought I would add one more bit of information as I figured out a little more info regarding current heads;

Turns out that the heads are World Products Windsor Sr Heads; 200 intake, 58 cc chamber, 1.25' single spring; weight of 55
at 600 lift, intakes flow at 272 cfm, exhausts flow at 191 cfm.

I called AFR to see what they would recommend for an update; they suggested 185 cc with a 58 cc chamber; and they flow nearly identically to the World Products heads...The sales person thought that the 205 cc would be too much for my application...? Sales person said I should pick up about 50 hp switching to these heads with current cam.
