Re: Starting my engine build

If your chasing threads with a tap you need to buy a bottoming tap not a starting tap, starting taps have a tapered start, a bottoming tap only has maybe one thread that is tapered, this will clean the threads in blind holes, probably $10 at my local hardware store. Open the link:

Re: Starting my engine build

I was taking a look at the heads that came off, and the number on them is 3991492. They have 2.02's and 1.60's, and a spring stout enough to run that Lunati that has .455 lift. After reading a bit about them, they look to be pretty nice heads. I'm definetly happy with the heads I got to replace them, but a cool find anyway
