How reliable are snout extensions for the fuel pump?

it's a real roll of the dice. likelihood is that it doesn't as that they were phasing them out by/around 87, and with it being TBI it would need hi pressure feed (i'm assuming).

rollers w/ snouts are rare as rocking horse ****

So I pulled the engine and the 46rh today . I haven’t pulled the timing chain cover off yet but I do see that it has a cover with provisions for a mechanical fuel pump and a block off plate . Which leads me to hope that it might have a snouted cam .
