I was looking at my manifold and the head pictures and realise the ports of the manifold are larger than the head inlet ports (34-36mm to head 30mm).
Will this step- not ideal- cause any major dramas with reverberation of the pulses?

I know lpg is more forgiving than petrol with flow- and I'm not planning on changing anything- just curious as it ran ok with the stock l series manifold (had a similar step between them too but only 1or 2 mm all round)
