Edelbrock / RHS heads, or go BIG block and put it to bed!

Thanks.
My average 60' times were 1.93 with slicks. I was going to put 4.11 gears in the rear for quicker times but I would like to get 300 hp to the wheels, and up my trq. Im just trying to tweak the car a bit for a good drivable street car.

cam is 489 lift

thanks for your you input

What E.T. time do you want down the track?
