So I'm porting my heads and intake ...the best I can...and noticed. The intake is brutal restrictive ,like the runners are small compared to the gasket? Should I port match the gasket? Seems like a ~~~~ load of material to remove. Is this normal. Also I'm sure it's been asked a million times but what's the gains on some heavy ported heads and intake . I'm also porting the SC inlet outlet and running a 90mm lightning maf 5.4 f150 modified TB I'm thinking 74 75 mm . Lots of air flow compared to stock. Is it worth the work? I've heard that it makes maybe 15 HP.
