I was wondering if the A6 head and B1 head are the same, like does the A6 just have a more aggressive cam profile or does it also have larger valves, springs, etc. I own a B1 head and can get another for like $50 so i was hoping that i could just put the A6 parts into it

the difference is in the cam and valve springs.

 

will the Si (A6) parts (cam and springs) fit in the head tho?

 

yea

 

sweet thanks a ton!!!
