People who say the lump ports are a waist of time need to go back to 1st grade and be fired from their job. Anyone can easily see how it makes a difference...just by looking at a stock vs with lump port picture....I mean c'mon! lol Even my machinist had enough brains to see the difference before he even saw it! Lump port that head and put some bigger valves in!!! If your not gonna overbore the engine or raise the compression I'd go no further than 1.86 for the intake valve and even leave the exhaust stock. Have the head shaved a bit for sure for a compression boost.
