Blow off in engine area when press gas

[XplicitReveals]

I just replaced my injectors..I was told that I may have a vacume hose off somewhere..

But when I press the gass it sounds like air blows off in the engine area like a quick puff and the car doesnt accelerate..

Also when at idle the car is rougn and acts like it wants to turn off..

What could the prob be..
I didnt have this problem until I removed the heads to get to my oil pressure switch..

if you torqued the head on in the right bolt pattern with a new gasket, it shouldnt be an issue. you could have tons of leaks all the way up. buy some gas in a spray can (engine starter fluid, etc) and spray areas where you think there is a leak, if there is a leak, it should affect the idle. sounds like a vacuum leak. check block to head, head to manifold, and all corresponding hoses. did you have the head milled when you removed it? if its an aluminum head it has to be re-surfaced before re-installation (50 bucks) or it wont seal right.
