b20z w/vtec
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?

you need to replace the B20 pistons for pistons with bigger valve reliefs. B16 valves have been known to hit the B20 pistons, VERY BAD. If you're gonna be asking 8200rpm from the B20 bottom end, you might want new rods too.

....hence:
really, to do it right, you'll need to do the whole bottom end... to do it OK, you'll need at least rods and pistons... to do it crappy, all you need is pistons (some peeps even do it without pistons, but high RPM = valvetrain death)
