should I match port my 396 oval port heads
I was wondering if it is worth going through the hassle to match port my stock oval port heads while I have the heads off to change the valve springs to a heavier one for a comp cams big muther thumper cam. and will it make a big enough differance if I do the porting the motor is a 396 with a air gap intake ,headers, 750 holley dp, 400 tranny ,12 bolt rear with 4.11 gears ,3500 stall, its going in a 68 camaro right now the motor is out of the car so it wont be a problem ripping it apart
