will J heads work on a 318? And many many more questions.

just port match the intake to the gasket.
Put the gasket up to the intake line up the bolt holes and mark where the gasket lays spray paint over the gasket
Then do the same for the heads and grind off the area that is painted
maybe someone else could explain better
if you are going with 3.23 gears use the performer intake mare bottem end
the smaller port on the intake is for the coolant if its in the front
Also on the heads you will have to get the guides machined out for the larger valves
basically just go to a machine shop and get some prices for this
really for a budget build the smaller valves will cut down on power but will still work
the best way to plan a build is to set the price tag amount first then the suggestions to as what to do and the power level are limited by that
