Yup, well in my case it was considering there werent any signs of threads ever existing in the holes. When I stripped mine, I made sure I got it all! lol. I didnt have any problems whatso-ever when it came time to run the tap through. I stuck something in the hole to measure the depth, matched it to the tap and used masking tape as a stop guide on the tap, and went to town. Held up just fine. Of course Im not running that head anymore...decided I needed a little something more for being good over the last year! lol Street RV head...Virgin Casting and all new Exhuast studs. New Headbolts too! <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" />
