I got a 95 civic with a stock b16 bottom end, just put a stage 5 cnc post-n-polished head on it, and now the car wont start.

The car has fuel and spark, turns over, just wont start.

The head has a 5 angle valve job, major port-n-polish, etc. but is running stock b16 cams. Could that be my problem?

 

double check your mechanical timing.

 

i have checked it twice.

ill check it again once more.

 

Do you have compression? Are all sensors plugged into the correct positions? Valves adjusted properly?

 

have not checked for compression yet, but i dont see how it could of lost compression with just swapping out a head.

all sensors are plugged up correctly.

and from what i can tell the valves are all adjusted properly.

 

ide say ur getting something wrong with ur cam belt. are u sure of ur makings and referance points

 

How long has the head een sitting. I just did he same thing on a motor I built and it turned out to be stuck valves

 

i would recommend checking timing and doing a compression test as already stated.

 

get a feeler guage to check the valve lash, maybe you bumped them and turned the screw on accident. But a compression check would def be the first thing I would check since it cranks over, it will be a hell of a lot easier than checking valve lash.
