ok. my car was running before i swapped the heads. it has a 96 gsr block. i had a gsr head and put in a b16 head. i am using the stock t/b and a edelbrock mani. i checked the timing. i checked for spark. i checked for fuel. i checked for ground and power. all it does is turn over. i pulled the plugs again and there was fuel on them, so i know its getting gas. the plugs are new by the way. any one have any ideas?
