I unfortunately have to rip the head again and replace the hg that lasted 3000miles. Last time i remember getting the egr plate free(and reinstalling) from the intake manifold was a huge pita. and the fitting on the exhaust manifold wasnt going to come off.. This is a main reason why i have been putting this job off, but its time to try again and get the 240 back on the road. I am looking for hints on the best way to get the egr off and back on when i rip/reinstall the head.. thanks

i just used a large adjustable wrench and heavy rubber malet to unscrew the fitting at the header once the egr pipe is off the header you should be able to unbolt the manifold as usual and the remove the head right?

Do you absolutely need to have the EGR installed? Why not go without it unless your state has strict emissions.

Is there a thre4ad somewhere about removing the EGR? I was going to do it when i swapped engines, but I didn't want to mess with the variable intake stuff that is in the same area.

Thanks for the link. I'm not going to do a turbo conversion so as I understand, the butterflies would be best left in. At lower rpms the will induce more torque. For a turbo swap it makes prefect sense since the boost at lower rpms will add torque, and not having the intake restricted with butterflies will help the top end.

Has anyone done a dyno comparison on an NA engine?

the way that i do it is i spray it with penetrating oil maybe use some heat like a propane torch. loosen the header/manifold and then use your wrench or vise grips or what ever you use, and when you install it put anti-seize on the threads. should work pretty good
