Default block off plates

ok i put in the longtubes but now have those hoses for the air layin around. i think theres 2 up front (rubber) that went 2 both driver and passenger side and looks like a hard flexible brass one in the back that went to the passenger side header. i heard that i need egr block off plates. someone point me in the right direction? I should have my ypipe by the end of the week and would like to be done with the exhaust. thanks

as long as you have race headers without air or egr provisions, you cap the hose (one on the air intake before maf, other at air pump) and you cap the egr hoses (vacuum port, hose to the egr valve itself, and the hose from the old header to the intake) then you should be fine. maybe you have a vacuum / air leak that needs to be capped off? or you know, i just remembered. the o2 sensor placement makes it run a bit more rich sometimes or so i've read, so maybe youre dumping too much fuel in. it doesnt hesitate at first but after the engine warms up it does? in that case maybe you should get a tune if the other things dont help fix it.
