Valves capable of suporting 270Hp on those but only with head port ex&in sides.
Being a SOCH D16 is for the first its a short stroke engine, it just never will torq as A20. With proper headwork on A20 and stronger valves and if you manage to find cam bearings that are stronger it will rew up to 8-9k with no problems, just give it enough air.
My conclusion is that if you have 1k USD on B18, then 400USD on axles, 400$ on clutch converter etc etc. total 2-2500¤ to spend on a proper build, then you can just as likely spend that money on A20 and boost it, it will be cheaper and stronger engine overall.
