more than likely is.... check intake first before pulling heads.... intake gaskets are more likely the point of failure.... and yeah, you'll have to get that timing retarded a little, its probably advanced a bit since you had it in your off idle circuit

yup pulled the intake manifold today and the gaskets are soaked. owell im learning as i go, i believe it is due to the fact that i got my heads milled slightly and didnt do anything to the manifold becouse i eye balled it and thought it was ok, guess not. so ill bring it to the machine shop after the weekend and see what they reccomend. thanx again for the info ill try to keep ya informed.

i used felpro gaskets the ones recomended by afr but i cant think of the amount i had milled out of the heads right now but i do remember the machine shop guy telling me that the intake might need to be milled. but ill try to find or think of the amount i had milled tommaro. sry for the grammer late party night post.
