I'll have to look at the serial #'s when I get home. I read somewhere about different heads that have different intake ports, can't remember if it was size or shape.
I'm not looking for a screamer by any means, I am very limited by the rear end in it and hoping to get tires for the original 17" rims. As I wrote above, I can't find traction tires in 17" that I like the look of. I have seen military 17" traction tires but just ain't all that thrilled about how they look. Not sure I want regular type front end tires on the back end either. Whenever I am done, I don't expect it to be seeing any snow.
