Here's what the rocker shafts look like mocked up on my engine (complete set of 6). I'm running stock rockers with a 215/220 roller with no problems. $50 shipped
The small round hole is easy. All you need is a pipe tap. The large one starts off as a rectangle so you really need a milling machine. It really cleaned up that section of the manifold. I was pleased at how well it turned out
I like to buy the MAF if still available i need it for the convetion im doing
On my 85 tt. Thanks (do i need a translator for that?) Or is it a stock MAF for 86/87?
