how do these stack-up for low rpm hi torques truck applications?:worship

You would be better off with a set of e-7's or gt40's .

funny, the e5's and e7 are interchangable they are the same head, just different casting numbers because of the ******* e6 in the middle

Basically identical head as an E7. They will make good torque but you are very limited.

I would have figured that the e-5 was an earlier casting like early 80's and smogged to hell . And all small block ford heads are interchangeable .
