What is the best 4v head for all out drag racing.

[BNblownsaleen]

I have been digging trying to find out which Head would be best for a all out drag racing 281 turbo application. Basically I have read that the Cobra R head is the best but obviously it's near impossible to get them. So from what I read it would be between the b head and 03 cobra style head.

I want to know what you guys think and the reason why you think that heads the best.

Also, this may be a dumb question but can you Run 5.4 4v heads on a 4.6. If so what intakes can be used. Thanks in advance.

Also curious if anyone has specs on the new coyote heads

I would think FR500 heads would be better than cobra or b heads.

So the fr500/gt500 heads can be used on a 4.6

How serious is the setup? livernois heads are very good. but not really for mild to low performance setups...

Right now I haven't bought the first motor part, I'm focusing on the car, suspension, cage, wheels etc etc. But the car is going to be full race, I'm building it to compete in a local 275 radial class called real street 275.

Right now I'm trying to figure what head would work best with a t76 air water ic. I have a very reputable head porter local, so I'm trying to find out what the best head to take him that has the potential to make the most powa

for forced induction.... I would just use a set of 03 cobra heads and have them extensively ported.
