273 Headers (weird combo)

318willrun said
I guess I was unaware that there are 273 headers, 318 headers, 340 headers and 360 headers. Maybe I've used 318 headers on my 340's??
:rolleyes: :eek:

Some headers, need to be modified to use the smaller ports on early heads. Forget whose, maybe TTI? Usually big is OK unless they leak.
