@Vee_Que thanks for the info. The motor I intend to buy from Berries is a squirter block and it just so happens to have the 531 head. I was planning to put in some H beam rods, double valve springs and either get some valve cutouts on the factory pistons or just go with some aftermarket option with the cutouts.
I have a cam and gold ezk unit on the way and stage 3 chips for both ecus from ClassicSwede (unsure of where/who Classicswede gets their chips from). I'll be getting the TTV flywheel and clutch combo from Classicswede later On, but I'm interested in the BMW pressure plate? Dai mentioned something about getting TTV to install different locating pins and bolt holes to use a specific pressure plate for clearance. Unsure of which one it is exactly, but I'll find out next time I speak with him.
Also, maybe you can help me with info about the cam. I was wanting to put it in with my b230et with the 9mm rods for now. I've been reading about breaking in the cam and was wondering if the break in process will need to be done again if I decide to put it into another cylinder head? And would it cause it to wear prematurely? Would it ultimately be worthwhile waiting until I have the other engine before I install it? I really want to enjoy it asap, but not at the expense of wearing out the cam unnecessarily.
