Almost in the 12's, new convertor coming is 4500 TCE so should definately get there, question is put on AFR 185 or 205cc heads or 200cc pro topline's or keep 430Hp stockies and run 347 stroker instead. Flow no's from pro topline heads outflow afr's until .5 so would/should make more w my combo Any input from the been there done that brigade would be very appreciated. also if keep 306 then topline heads better at 58cc chambers but afr's are 60 so will need to mill to get comp, can they be milled enough to get down to 53cc (afr say .018" which is 3cc). Also anyone got some 4.11 gears for an 8" thanks

Should just forget the lot and put 200HP of gas on it

Protopline are o/k..Remember if you machine heads down too much you'll have issues if you latter want to stroke it...
Flo rates
AFR[185's] 189[153 exh] @300 lift / 267[185 exh] @500

Protopline..
180cc 208[159 exh] @300 / 271[193 exh] @ 500 lift

Both good heads no point in going much higher than 500 lift as most street cams don't go much higher than that.....

Sounds like you just wanna go fast in a straight line. Very expensive options to just get into the 12's. I think the easiest and cheapest way would be the NOS.

You will have to be quick. Rumour has it that Pro Topline has gone belly up..

Yeah but feels like cheating, want it to go hard on the street ALL the time not just when bottle is full! also heads will be good when upgrading to 408 351w stroker in not too distand future (illeagle too!)
