Even a Bosch 910 pump is a bit much on a NA 4a with slight mods - ran one on an SR with 300+ hp no worries.
044's are as said, Noisy - and massive overkill for any NA 4ag.
Bosch 070 would be your pick,

The only thing to watch out for in both Bosch and Walbro are the Copies going around.
So just pay the money and buy it from a shop and not ebay.
