a few ???

ok guys , i replaced the nozzels and needles in my carbs. i all so replaced the fuel pump. still smoking at the tail pipe. it actually made no differents.other then to my wallet.i noticed that the fuel mixture is much richer well more turns down now with the new nozzels and needles then my old one's and i made no other adjustments. maybe i had .100 nozzels instead of 0.90 . or have i got one hell of a vacuum leak . i removed the hose from the pcv valve and i got no blowby should there not be some gas emissions coming out of the block vent tube that goes to the pcv valve? also should here be vacuum at the valve cover vent tube when the car is running ? any about ever had stop up oil passages in the head ? when i bought this car the oil smelled liked gas. but my float blow levels are not high. and the car runs very smooth . this is a f54 p79 head . :stupid: thanks for your help.
