| FE 2v heads vs. 4v heads |
| By Lane Monden - 02/20/2004 10:32:13 PM; IP 63.173.3.73 |
Is there any difference in the 2v and 4v 390 heads. I have a pair of C8AE-H and a pair of C6AE-U. The 68's are at the machine shop and I am having them milled .030". Will these heads perform as well as 4v head? Is there any difference? In the book it lists that all 390 heads have 202 int. and 155 exh. valves with 67- to 72cc combustion chamber. Look the same to me. Any info is greatly appreciated.
