Is there a good place to find info on the max limit on head warp I am debating on buying a 91SC was driven hard and had multiple head gasket failures. 59k miles good car but I think something is warped it overheated then the guy slapped new gaskets and a reman blower among other parts on and called it a day less than 5k later its puffing white smoke thats noticeable but not blasting out. Need to now how to approach this because its $500 and there isn't rust and there are a few other goodies on it. Also is there a walkthrough on the swap? I have the Chilton's but pics would be helpful. Also the car comes with 17" Cobra R's so I just need to know what to do once I get the old heads off with checking if they are junk. I can pull the heads off there and check out the problem before I commit.
