I recommend if anyone wants to do the 360 1.88/1.60 heads on their street 318, that they use a dual plane 'or more gear', have as high compression they can run on pump like 10.8ish 'quench dome would be nice, and keep the cam's O lap right on the edge of letting ping as to get max torque/hp for the combo/comp [around 62-66*], and of corse ...the most initial timing it'll take with what ever it likes for total 32*-34* er what ever.
And if porting, beyond 245ish is gonna make it worse cc wise, it starts getting big in there.
