MMS 220 Build for "Ghost Hawk"
Well, I pulled the trigger on a build. I have two goals on this build:
---1. Get at or near 500 HP on stock 5.7 cubes N/A - Last Dyno 539/441 Jan 2018 -- RIP Feb 2018 due to excessive oil consumption
---2. Daily Drivability and reliability
---3. Numbers here: https://ls1tech.com/forums/generatio...l#post19482485 - post 481
So, here is the build list:
1. MMS220 heads - mamofied and fully assembled by the master himself
...1a. 2.055 hollow intake valves
...1b. AFR 8019 springs
...1c. Titanium retainers
2. 040 MLS head gaskets
3. Johnson short travel lifters with link bar --Replaced with LLSR solid lifters 6/16/2016
4. Manton custom length 11/32 x .125 pushrods
5. Yella Terra rockers with 10mm bolts
6. Fast 102 - mamofied - --Replaced with Mamofied MSD Airforce
7. Nick Williams 102 throttle
8. Maziere electric water pump
9. ATI underdrive pulley (long overdue)
10. ARP hardware
11. Lingenfelter 100mm MAF --Deleted and running SD with 4" silicone intake tubing
12. Cam will be the current cam in the car 227/236 112+3 --Replaced with 237/245-112.5+2 6/16/2016 with LLSR. After car warms up, actual profile at valves (minus lash) is 232/240-112.5+2.
Future upgrade paths to include:

I normally suck at documenting these things and then get mad when I didn't do it. Here's hoping the thread keeps me honest.
MMS 220's still in the box. Should have come in green and red wrapping paper
Top view. The first thing I noticed about these was the size of the pedestals and the lack of razor sharp edges around the surfaces. Yes, folks, you do NOT need a battle suit to handle these heads and avoid looking like you were mauled by a cougar. Note these are 2015 AFR castings, part number 1710
Plenty of room to exhale on these things
And also plenty of room to inhale. No breathing through a straw on these babies

And more viewing material for your next one-handed trip to the bathroom (or wherever)
Here is where you really start to see the level of detail. I kept the camera low to show the whole port, and you can STILL see most of the intake valve. If I took the picture from the rafters of the cathedral, you can see almost all of it. Straight shot to the combustion chamber from the manifold
Here's a shot looking up at the roof so you can see the rocker boss on the right and how much contour went into the intake guides
Deck view.
One last shot to show the bowls There isn't a sharp transition anywhere. All nice and buttery smooth.

So, once the lifters and rockers arrive, I'll be able to start the tear down and get the measurements for the pushrods and then start reassembly. Hopefully in the next week or two

Very nice parts list and I am very much looking forward to the results. One question though. What made you go with such a large intake to exhaust split on the cam as Tony usually goes with a 4-6 degree split.

Good question. I had three reasons. First, my exhaust isn't duals, and the merge pipe isn't the best so I wanted more duration to compensate. Second, I wanted to stay in the 227 range, because I tend to see that as the sweet spot. Diminishing returns above that point - you start giving up more for less gains. Third, I wanted the overlap to try to carry power past peak without giving up too much down low.
When I was picking it out, I couldn't decide between the tick SNS2 or the cam motion Titan 4. I knew I wanted to stay near 227, because I paid attention to Tony's builds. Kip split the difference on the valve events and this is what he arrived at. It's a great cam. Even on a BBK intake and mildly ported stock heads, it pulls very hard and carries to 6800 rpm. Has great partial throttle response
Hope that answers the question.

I remember Tony making a comment about "out of the box MMS 220" vs mamofied, so I'm thinking they are a proprietary 220cc casting and the rest of it was the mamofication. You can't see from the pics as well as you can in person, but there were places the tooling didn't touch.

You could also use the 2013 Nissan Altima pump, but the servo motor they use makes this annoying whine. The MR2 was quiet.
Should free up more than the maziere water pump, since the fluid is more viscous and under higher pressure.
