Cylinder Head Specifications
Note Time-Saver: If you are on a PC, use the "Find Box" to search for a specific "Cylinder Head Part Number" or whatever your looking for, on this page. Hold down the Ctrl key, tap the letter F, type or paste in a word, words or numbers in the pop-up box, then click in the box, next or an arrow.
What ever you typed into the box, if it exists in 'that sequence' on this page, it will be highlighted through-out this page. It saves you a lot of time scrolling down the page to find what your looking for. It's a great tool that can be used on any webpage.
The information below came off of a M-M
service news letter. I hope it is all
correct with my transfer
to a webpage.
