Wondering if anyone can help me with figuring out what I need for this swap or if the swap will work I have a 01 4.8 ext cab stepside found a lq4 6.0 seller said it had the old iron heads on it but will be putting 799 heads on it wondering if it will work with a 4L60E or have to get a 80e coming from a 2500 gmc Sierra 2000ish
