Hey I found a guy that will trade me a b20z block for some old parts I have. If I get it I'm going to put the b16a2 head on it. Now I know the b20 wasn't built for high reving vtec. The guy owns a shop in Maryland called EVOLUTION MOTORSPORTS and he said that the only failing point on this swap would be the head bolts which he woul replace with ARP.

What are some disadvantages to this swap?

Do you know anyone that has had problems?
