				 GT40 aluminum heads 
 I will be pulling my SVO 351 and stroking it to 408. I really want to use the existing parts if possible. The car is primarily driven on the street, with my rpm's staying down most of the time. I want to stay with my aluminum GT-40 heads. Are they sufficient for my mostly street driving, with the 408 displacement? My engine builder advised that he can port them if needed. I am also running a victor jr. single plain intake. |
