My friend bought a turnkey 454 Gen V block to put in his jet, took the electronics off, put a 80's model factory intake (spread bore), he used factory intake gasket (#90665)
I was informed that we may have an issue with water not traveling throughout the block and heads correctly? heating issue? I was not around during installation, also intake seems to be from the 80s? do we have a problem or not, would like some info on correct gaskets, if we have to pull it, I will not be putting that lo-rise factory cast intake back on, headache for throttle linkage and cable.
