why do you ask ?
how much power do you want to make ? the more the boost the more the bottom end will hate you ... the head will be fine ... the "head" is more affected by raising rpm limits than it is by having boost in it... the thing is say you want to make 300hp out of a 5sfe... it will take ALOT of boost on the stock head.... if you cam it , or oversize the valves, or port it properly it will take less psi to make the same hp figure... that's really how the head comes into the equation... -------------------- 2005 MB C200 Kompressor- K&N, Apexi WS2 Catback, DIY Voltage stabilizer, Intrax Springs, H&R RR swaybar, VDO Boost Gauge @ 6psi, Greddy L7 plugs, +0 Rear tires
