Ported X head pics
Some one had a PDF file of them templets that was accurate and to size. There was some setting that you had to set your printer too to make them accurate......landscape i think. I was never Successful with a Quality printing of them.
Back in the day when you could buy the plastic W2 temples i bought them and then trimmed them to fit the hardened intake seat. That i had to have installed to save my head i had to have to save my head. Ported that port and then ground down the W2 templets until they fit my port. So that i could match all the rest or them.
That was long before i knew anything about a 88-91% bowl to seat ratio. these were 1.88 intake valve heads.
