89 2.8 tune port fuel injected

I Have fuel pooring into the oil pan , I have just changed the timing chain and gears and also pulled the heads to extract 2 broken exhaust bolts , replaced all gaskets with a felpro complete head gasket set . and used a Chilton's Camaro 82-92 repair manual for referance and torque specs
When first tring to start the car it would'nt start or even give a sign of tring , tried till the battery was dead , so on the charger it went and left it over night , next afternoon it fired right up but smoked real bad (white smoke ) and no power real sluggish . and also noticed oil coming out of the top of dipstick tube .
Thought maybe I had the gears set wrong so I pulled the front cover back off and checked them , had #1 TDC compression stroke and set the dots on the gears both at 12 O'clock pin in the top gear was fine and the keeper on the lower was also fine .
When pulling the front cover off is when I noticed the oil , more than a gallon came pouring out from the front of the pan , and smelled strong of gas
Any Help or advice please

 

If you didnt have this gas/oil problem before you did this repair then I would look back into the intake gasket or the head gaskets.Something isnt sealing
