The only thing i dont like about magnum asp sc ect. Is the valves leak in every single one i own , i think the problem is valve warpage or it leaks between valveseat and head

Good Engine I gave you, Except I could not get it to idle for a long period of time. It would start to load up

I finally ran it Marlen! It flip started immediately! Im waiting for the issues to start showing up.
