What to check to reduce MPG?

Currently my car is eating fuel to the tune of about 16mpg in mixed driving that was with 2 or 3 vtec blasts
So far i have changed:
Fuel Filter
Manifold
O2 sensor
added the cat back in
different exhaust
But it's made no difference
Once I have my valve tool back I'll redo the valve clearances, also need to do an oil change
What other things can I look at?

If it's already full of bullet holes, there's your problem!

Getting worse, but it's never been excellent on fuel, always thought it was my right foot
