I just had a buddy call me, and he found a guy with a complete set of 781 heads for $20. He just wants them out of his garage. So I gave his wife a twenty, will pick them up in the next week. Everyone is touting aluminum heads, and I know that they are beneficial, but cast heads are propelling Chevelles, which weigh more than Novas, into the mid-10 second range. I am stoked to get these home and look them over. In a year or so they may go to the shop to get HOGGED OUT and ready for a big cam to match!
