can someone tell me what kind of head I have 64 330 I believe as ive stated in other thread is a low compression 2bbl engine the code # is T087349 now according to 442.com the first (T) This code consists of a prefix letter (330 V8=T(1964-65) then a production sequence number but here where I get confused it says followed by a suffix code letter (L = Low compression, E = 2-bbl export, G = High compression, H = 4-bbl export). if the code I found is the right code how come there is not and letter at the end I found it stamped on the front pass of the head can someone help thanks
