Engine pulsating.

[danalyse]

After about two hundred miles after I completed a head job and after the car sat for a couple of weeks, I decided to take it out for a spin before the seasons ends the vert that it is. Once warmed up the engine is pulsing between 1500 and 2000 RPM. Any ideas?

Any spots to look at first. Any suggestions as to procedures in attempting to find the leaks. When I put the intake manifold back on I made sure the surfaces were clean and used some RTV silicone.

RTV in addition to new gaskets, or just RTV? RTV alone might not result in a seal.

You need to check all the hoses also.

All new gaskets. Seems to be a minimal amount of hoses. The big accordion like piece, The hoses connected to the break booster and the one going to the fuel pressure regulator. Am I missing any others?
