| if i recall correctly,after 65 the head ports were dropped 1/2 inch on all bb except the 427,428 cj,but the bolt holes matched,not the port location,i found this out when i put 428 cj exhaus manifolds on a 67 390 mustang,disaster followed,back to headers and the motor came back to life,match your port locations to the manifold/headers,why don't they make a header that covers both locations,the early ones did,i e my 66 fairlane with a 427 tunnel port(transplant)made by doug thorley,and they criss crossed oil pan twice,they were supposdely (tuned) to firing order,and that you could remove one tube to access the starter,try that with heddmans on a big block,not familiar with the other vendors,maybe some good stuff out there,check before you buy |
