    grinding complete on the intake a couple more mods then its off to get ceramic coated black today

    burr finish throughout, doesnt look flashy but the engine only cares that it functions, plennum has been modified with a custom spacer milled to suit, runners match ported 1mm smaller than head entry, the 4 center runners received most of the work

    Please excuse my ignorance but I'm just wondering what the benefit is to match port the inlet manifold runners 1mm smaller than the head ports?

    Isn't something to do with getting any fuel droplets which have collected along the runner walls back into suspension?

    a couple of reasons which have been mentioned above, when the intake runner is 1mm smaller than the head entry it is still larger than the pinch area so its not limiting port area and doesnt hurt flow as much as you would think, has minor anti reversion properties and allows a little movement when fitting the intake without uncovering a port, this is how we do most intakes, race stuff we do a little different

    yes to the OCD....LOL

    its not that hard to maintain the cleanliness, one thing i cant stand is working in clutter.....i just cant do it, especially when it takes such little time and effort to keep things organised

    1st rule is nothing dirty goes in the engine room, we have a disassembly area in the workshop where engines are stripped and then parts go in the spin wash, when going from porting area to flow bench heads are blown off and brake cleaned so we dont put dust through the flow bench or in the engine room, the other thing is its easy to wipe a bench down with a clean rag before you lay parts out it when the bench isnt cluttered with crap

    i also put tools back while im working its easy to do when your tools are only feet away from what your working on just open the drawer use the tool then put it back when i have tools out i put them in a steel tray besides the job im working on or on a rag so its all in the tray and you dont have to go through clutter looking for tools, i do the same with parts, put them in trays and if for some reason you have to stop that job and move onto something else you just put the whole tray away in a cupboard with all the parts in one place, i actually find it easier to work faster when things are clean and organised.......cant say the same for life outside of the workshop though im hopeless

    rocker pedestal heights set up to give us a narrow and centered sweep pattern, i machined the rocker pedestals a little to get the height spot on, this all depends on valve length and the amount machined off the rocker stud boss

    You'd break down in tears if you saw a mates workshop, he's a capable machinist and a great bloke but his workshop's a s#it fight and there's no "engine room" as such. The guys who work for him used to try cleaning up each week, he'd be in for a day on the weekend and when they got back on Monday it looked like they hadn't touched it so now they don't waste their time and just put up with it, I'm stuffed if I know how. I've spent a bit of time there on occasions and I struggle and my OCD level would be well below yours.

    Thanks for the input on the inlet runners guys, I'm always happy to learn! All this time I have been making sure I get mine the same as my port entry, thinking the smooth transition has to be the best.

    Just remember an inlet tract is at least a two way street.
