Im buildin a little ghetto *** a6 built head. Ive cleaned up the valves and was grinding them when i noticed the a6 valves and the extra d15b2 valves i was gonna use are different. the b2 valves look thicker but both measured the same on the dial caliper. right before the stem curves to the valve seat there the valve becomes thicker where as on the a6 valves they are straight stem to valve seat. From what ive read and been told is that there is suppose to be no difference with parts but it looks to me as though the b2 might be stronger,true. ether way im gonna need two more b2 valves or 4 more a6 valves. which ones are stronger?

hmm thats odd, in my a6 Na build I had to use about 5 valves from a b2 head and they swapped over just fine, I inspected all of them closely and (had them recut) but they all looked identicle.
