Well guys I found out that the tick I had was a valve tick. I'm looming for replacement heads or a cheap way to redo the heads I have. I have to much in to the car to sell it for a lost. I really want to keep the car. I've found a seat of junkyard heads for $50.00 a head. J know that's a good deal but those heads are unknown miles and I don't want to deal with this a month later if they are high miles heads. Anybody know what a valve job runs. I really want to keep the car and build a respectable Sixers. Everyone around where I live drives Honda's and talk crap on Sixers. I would like to so them that GT aren't the only mustangs to respect. Any help would be great thanks guys.
