So I am planning my b18b set up. I have everything in the head planned out except for the valves, mainly because I cant find alot of info. So here is my plan so far Crower 403 cams $350 Crower Dual Valve Spring and Titanium Retainer Set B Series Non-Vtec(84162) Portflow Port job. Now what valves. I am guessing that the stock valves would probally drop with that stiff of a spring plus 8000 rpms. Any suggestions? I am looking for a semi inexpensive valve.
