just headers and custom exhuast decided to put on a new intake and carb

not sure where its coming from but the shop where its at is having some problems

maybe at some point the heads where decked. or someone ordered the wrong parts. tell them the easiest way to find out exactly where the leak is coming from is to run the motor and while its running spay some intake spray around the intake in small spots at a time and when the engine idles up you'v found your leak. if its leaking the whole way around someone fucked up somewhere.

also works with a propane torch thats not lit, turn the gas on and when the engine revs up thats where is leaking. Keep away from sources of spark.

If you heads where decked, they would thereotically become shorter therefore how the intake seals in the bottom cornres the gap will get bigger, causing a vacuum leak.

ill come drink beer with you when my truck is all together. Motor is back, new head gaskets(basically best money can buy), re-wiring of the whole bastard is pretty much wrapped up, now im putting in some new gauges so my motor is kept in check... slowly.

I might be able to steal pops jeep one night and swing by.
