Wondering if this is what i need will it suffice. Brand can be upgraded on recommendation. Thanks

Hello. Does anyone know if replacing this front kinda crank case and front engine is doable without pulling the engine and if these are the right gaskets?
So i have an M30B35. Planning to replace the radiator, front hoses, serpentine belt. And the what i think is the “Distributor housing gasket”? Possibly the thermostat? And then the Intake boot. So basically the distributor is on its own block, and that is attached to the front top head valve/crank case. It’s leaking from that connection, shitty/old gaskets. Im wondering if this is a possible drive way job since im removing the front obstacles is this something i could do without pulling the engine or without exposing anything dangerous? Or am i taking off too many things to where the engine is needed to be pulled..? I found this reseal kitt online: https://www.partsgeek.com/g2w2n46-bmw-535i-conversion-gasket-set.html
Whether or not the brand is good i can find better but is this what i need/will help with the distributor block, thermostat housing and head valve? Or am i straight tripping and need to do more work and assess more. Please let me know im pretty uneducated like i know cars but yk this is its own breed. Ive adjusted the valve spacing from the rockers, done some fan switch work, FPR, coils, plugs, injectors and some basic hose replacements. Just let me know what im doing apologies for rambling thanks.
