Where to buy Heads
The eddy heads are decent ball park head,and claim to flow
[email protected] in gods name are you going to run a 600 lift cam in your car? What is a resonable cam for you to drive on the street and track.First question,give a percentage of street use and track use,80/20% split,if so,you have a street car that you take to the track a few times a summer and have a blast.The secret is having a cam and head to work together,not having a cam to big so you need a pro stock port,or a towing port that is the size of dime.If you check the spec of the flow at .500 lift,and if you use a cam of the .525 range with proper duration,you will flow better with a well done set of 452 heads and save a s#*t load of cash as well.Bigger is not all ways better,a head with stock valve size and great velocity and flow will out perform a head with big valves and have better alround performance through out the entire rpm range.Your rpm range is set by some factors,port flow,intake,carb,rotating weight of the bottom end,etc.Your 6 pack rods,the heaviest rods out there,you can shed tons of rotating weight by using a normal rod.Your max rpm,will be around 5500-6000rpm,and the 3.91 gears are alright if you have 28 inch or higher tires and good traction,any thing smaller,you will be the smoke show king,and the local tire companies best customer.If you are using a 440,and are going to cruise the car on the highway alot,you going to find a well tune iron head with bowl and port work will be more benaficial to you in the end.Also,the eddys head loses 1.5 compression pionts as compared to the iron head due to the alley head sucking out all the thermal heat from the comustion,that is why the camber is smaller than the iron head.Do your self a favout,call bobby and spend the half hour and talk,just talk,and learn why and be wiser than all the others and reap the power from the iron head,all the super stock cars can,t be wrong if they run in the 9s,10s,11s.Mrmopartech
