Fast Burn heads and superram compatibility.
I plan on building a 350 with a zz4 shortblock, fast burn heads and a superram. But I heard that the lower intake ports and the head ports won't match quit right or need some port matching, is this true? If it's only a slight difference than I won't worry about it but if it's going to require a lot of fab work then I will look into other options.
Also these heads have two different style bolt patterns, standard and vortec I think.
Thanks, Chris
