Nearly all engines now are Schneurle ported and they use angled ports to aim the mixture up towards the cylinder head which is why most engines have a flat top on the piston now

the above is not quite correct schneurle porting has ports on three sides of the cylinder,front,rear and opposite the exhaust.in the case of side exhaust engines.usuallt yhe timing of the engine allows thwe front and rear ports to open just slightly before the third boost port which keeps the charge from going out the exhaust and no need for the baffle.
