im not a genius but i dont see how hand porting can = perfect flow charts across the ports… thats almost imposible… i can see you getting perfect with using a flow bench and porting a lil here and a lil there… but from just doing so and then pow its finished… i doubt it… but if it is so… i say more power to you… i would kinda like to see what the flow is on those heads though… just to see… ---

There aint no freakin way and to do what he did to ur heads aint going to help much. U were better off buying ls6 heads or getting a set of 5.3 heads and bolting them on. Many people have tried to do what he did to those heads and they didnt accomnplish anything. most shops will get the heads cnc and the polish them afterwards. what he did was a waste of time.

Where do you find that Dart hand finishes their heads to equal flow for each of the runners? I think one of two things. You just made that up, or I suck at the internet. ---

You never even started arguing. Not a single point was brought up by you. You wanna come on and say CNC machining is better and thats your argument? I have not had a chance to make a comeback to your useless rants. Like I said before, your way off topic and pretty much have no clue what the current debate is about. So, since your done arguing I going to have to take that to mean your done flaming on a subject you’ve proven to have inferior knowledge of. Either that or you have no reading comprehension. If you weren’t stupid you’d probably have understood that I’m well aware of the benefits of CNC. So in due time the dyno numbers will be posted. For the mean time you can just take to customers satisfaction level as proof positive of the gains. ---

> [@Breakfast Survey for Project](https://forums.speedlife.net/t/breakfast-survey-for-project/26901/35): > > The idea of having a smooth finish on the runner is much debated. The idea of a rough surface on the ports it to premote a boundry layer of air that isn’t moving. Not a bad idea in theory. Now if you take a maganifying glass to so called polished ports there are still going to be alot a surface abrasions that will create a boundry layer. The injector is aimed at the back side of the intake valve spraying atomized fuel at 50psi. You are not going to have fuel dropout. The holes in the runners probably doesn’t need addressed unless you have absolutely no research in lsx heads. There was a cast in lump in the top of the runner where the base of the rocker stud bolts in. ok… i think the injector design is the main factor when atomizing the fuel… the layer of air over the abrased surface will cause the ‘air boundry’ that is talked about, but most sense would be to take a lowered grit sand paper perpendicular to the intakes airflow, so that you don’t get fuel drop ‘runners’ that allow the fuel to pool in the direction of the airflow, right?.. then again, a lot of that has to do with the method used when polishing and the direction it was polished, ect ect… i have done no research in lsx heads… just asking questions ---

although i’ll admit i know nothing of ls motors, i’m pretty sure the injectors spray almost directly at the intake valve meaning the intake roughness/smoothness is not much of a concern. now that changes some when you get rid of the fuel injection and add a carb. the heads were never meant to flow fuel, only air. ---
