Are Speedmaster Heads Good? I've Heard a Lot of Bad Press on Edelbrock 340 Heads Lately

My first suggestion would be to get the car down to 3000-3200 pounds (closer to 3000 the better) and get the chassis right. At that weight Edelbrock or Speedmaster heads can get you there with porting.

The car is 3,000 by itself the rest is my big ***, but there is a lot I could do to take weight out of the car and me. The car has a 10 point cage and sub frame connectors with Caltracs and slant 6 bars in the front with 90/10 shocks. It seems to work fine creating very similar slips if everything else is in order.

Is there any recommendations for who ports Speedmasters? I emailed IMM years ago and they didnt respond.
