My motor is a 402 ls3 motor. The heads that are on it are a 821 casting number. I have a buddy that has a used FAST 102 intake that he is wanting to sell. The part number is a 146102. Can someone tell me that this intake will work on my engine for sure? It says for rectangular port ls3 heads which from what i have been told is whats on my motor. Anyone know if this particular intake will work on 821 casting heads? Thanks in advance guys.

If 821 heads have rectangle ports then that manifold will work.
