I'm only using these heads because they are in better shape than the other ones. I really am not interested in drilling holes etc. I think it will work with what I have. Kind of practice heads if you will.
There are indeed some differences between these heads and the regular ones. I have to use different plugs etc. but it is mildly inconvenient.
No machining. Just going to run them as is.
that's what I did 20,000 miles ago. but I added the whiplash cam/lifters/springs when I swapped heads out for fresh VJ on the car set. I have the MH#452 with fresh VJ for my 78 new Yorker 440 = I need to look what heads it has now.
use what you got even if it is a 318...LOL!
