Okay, after much debating i have decided to ditch the 390 heads as i would have to spend 400 bucks on pistons, 250 on rebalance and still have to rebuild the heads and this is after i spent 6 hours porting one head.... BUT!!! i can get a set of 781 heads bare for free. I have heard these are some of the best oval port heads gm ever made. Are they all the same or are some different? are the exhaust ports rough on these and could use bowl blending and typical porting?
