I have a d16a6 block with a d16y8 head and I am looking into putting a cam in it. My question is do I need to be carefull with how big of a cam I go? I know that this swap has really high compression and I don't want the valves to hit the pistons. If any one can help I would appretiate it. If anyone knows what duration or gross lift I should use please let me know that also. Thank you in advance.

 

Find a compression calculator and calculate your exact compression before you start looking for a cam.
