Just bought a set of BS heads off e-bag they will need a little repair work but its very minor just wonderig what is the best intake to run on a low deck motor. what kind of flow numbers can you get out of these with out any welding or getting to crazy with the grinder



All depends on what you want. I like taking them to MW size and then they'll go 330cfm pretty easily. Give us more info on the engine and intended purpose.
OOTB they flow pretty poor by today's standards.
