HO 351w heads
Hey!
Is there any reason what so ever that the mid 80's 351w HO heads are better than any other say '69-up head?
I hear guys all the time refering to their HO heads when the swap them on a earlier 351.
Set me straight.
thanks!

Thanks for the reply but what are smog ports?
I have heard of smog humps
in the exhaust port to alter the turbulance.
I am askin about the 80's HO 351 head anyway.
Is it better,is the question.
thanks.
