thanks. that helps out alot. since it appears that i have a a 4V block, someone must have put 2V heads, intake and carb on it. is there any way to identify the year of the these items? (it seems like they are not originally from the motor) i am guessing that the heads, intake and carb are from another motor. the heads do have the "2" raised number in the corner, so i believe they are 2V Cleveland heads. if there is any way to tell the year, please let me know. (maybe the numbers on them? if so let me know and i will post them) ...thanks
