Changed intake gasket, now it won't start

remove no. 1 plug , unplug coil wire, bump engine over with finger in no. hole, you will feel whoosh of air on firing stroke, hopefully your harmonic balancer says ur close to tdc, i usually set balancer to 10 degrees btdc, put in distributor, hook everything up, make sure 5 and 7 arent crossed, we've all don it i,m sure, hopefully it fires
