Ok so I have a 95 honda civic and its still pretty much stock. And I recently found out that it needs serious head work. Would it be better just to get a GSR head and bolt it on or should I just get the B16A2 engine Ive been wanting to get? still a newbie at this kinda thing but Im learning.

 

you need a full swap. you cant just slap a gsr head on your d series block. use this time for a full b18c1 swap.
