Next question:

Apache (6.4L) heads on a 5.7L block.

I read that a bore notch *may* be needed, but everything I read is regurgitated second-hand info. No first-hand accounts or pics of the required notch.

So to notch or not? That is my question!




Come over and tear down one of my 5.7s and you can check it. im to busy
