i have bin told MSD are very good. but its a long way from me and id like a mapper that i can take my car back to from time to time as i upgrade the spec. so london area, not somewhere 150+miles each way.
there is a hole designed in the head and block which will not vent to where yours is,(opposite side) it has its own section in the rocker cover.... sealed by the gasket.
the breather will still work in effect, but the crankcase pressure is going to have to vent up through the return drain for the head......which isnt as good as it could be....
