I want to upgrade my 351w's heads. The engine is a stock, recently rebuilt 1996. I will be putting it together with a new low-end-torque cam. For heads I am looking for input on a couple options:
IRON HEADS
1. I currently have a recently rebuilt set of E7TE stock heads, I could port them....but they just aren't cool, I really don't want to use them....Cost: ~ $free
2. I have a set of GT-40 iron heads on an Explorer 5.0 that would probably need rebuilt, but they aren't that cool either ....Cost: ~$350-500
ALUMINUM HEADS
I am not looking for anything too radical, something like Edelbrock performers or AFR 185s. Something in the 170cc-190cc intake runner volume with ~1.90 inch intake valve. I want to avoid anything with a 2.02 inch intake valve because I think it might cause interference with the piston. I have also heard that the 2.02 intake valve might flow worse then 1.90 valves because the cylinder wall shrouds the valve more.
1. Cheap (~$500) Aluminum heads from ebay, I worry about them being durable and most of them come with 2.02 inch intake valves.
2. New Aluminum heads, ~$1000 Is it worth the money to save 50 lbs and gain a few HP over the GT40 heads?
I have been looking on Corral.net, I have not found what I am looking for yet. Does anyone have a set of aluminum heads they want to get rid of?
