I ran into 2 issues; # 1; The intake will not be a put and place bolt on. If they take off the block surface then they " have " to remove from the front & rear rails or bolting becomes almost impossible. # 2! ; Pushrods. I chose to go with adjustable 273's. Pushrods are now too long. So now I have 2 choices stay with the adjustable, or go back to the non-adjustable ( stock ).
