do a pocket port on the heads you want to use... thats real easy to do.... the conv will make a big difference as well as the chassis set up... if your looking to go 12.50 in the heat you need to make it run 12.30 in good air and I'm sure some of these guys are telling you the best they ran... you need more gear but use what you have... the 509 might get close with the porting... also do a match port to the intake and heads... with your die grinder knock out any chunks in the runners and just smooth up the short turn on the heads... if you can have the heads milled some to clean them and make them flat will help... get the front of the car as loose as possible so it lifts and get some rancho 9000 shocks for the rear and I think you'll get there.... use your 850 carb
