runs like a vac leak

Some time back I started a new motor..never has run well..runs like I missed the intake gaskets..iv did a comp test and came out with 155 pretty much across the board..runs bad cold and as it warms it gets better but still runs like a vac leak...in the garage or out it really stinks up the place..fowl unburnt fuel stink..when I started it months back I wrote about the pvc valve pounding ..iv replaced wires plugs dist ign box coil ..just runs like s#@t..so today I made up a leak down tester and did some testing..i made the one on the net with a .040 thru hole..first cyl number one with 100 pnds pressure it read 40 pnds plugged in...moved to 4 it read 36 pnds...both at tdc..thes are j heads with less than 1000 miles..so I moved to the rear and put my ear up to the e x pipe .no air escaping..pulled the oil fill cap on the val covers and I could hear air escaping..there wasn't a wind storm there, but I could hear the hiss of escaping air..what ya thiunk...all welcome
