for a stock 98 LS1 head.

 

65 or 67 cc's? I have forgotten so much. <img src="graemlins/gr_cry.gif" border="0" alt="[whiner]" />

 

everything I have seen or heard says 67.3 cc. just wanted to make sure. I needed to know cause I am having custom J&E pistons made to lower compression down to 9.2:1. Beleieve it or not I called MTI and they said 62(they also said their stage 3 heads use 66cc)- WTF I then called Lingenfelter and they said 67. A couple of places on the web also said 67 and the shop who is doing my work also said they had heard 67. Oh yeah Thunder Racing also said 67.
