Milling Intake to fit new engine
Got a 414 SB with Eddie heads. Heads were milled to 62cc and block was decked to 9.588". Intake is an LD340. I am going to run Felpro 1213 intake gaskets which are .060" thick and compress to about .050". With NO gaskets on I can get all the bolts in by hand but two are tight. All the bolts ride right up against the lower bolt holes indicating the intake is slightly too big even without any gaskets (see picture). Looks to me like each side should be milled minimum .060". But I believe .080" or so would probably leave the bolt right in the middle of the hole once torqued. How much should be milled off to make this intake fit? I prefer not to mill the intake side of the heads.
