Your big head is a good start for 21? RWHP, but it has to have the proper match of other parts to do it. Chip, header, 48mm TB, AFM, Injectors and 284/276 Schricks properly assembled is a proven way to make good power. See Gustave’s web site for good documentation on how to do it (http://e30m3performance.com/).
Also note that the evo3 intake cam is no slouch. I managed 214 rwhp with a similar head., Evo3 intake cam TB, AFM, ‘real’ custom race chip. Sure the Schricks were better but… well… that was many engine revisions ago.
If you want to get into big dog territory (235+ RWHP, 280-300 flywheel) I recommend you pay an expert like a Ron Checca. A person can easily spend more money experimenting and still never get there because it takes a lot more than just a list of part numbers to accomplish those numbers.
