critique my setup... let me know what you think Most of the parts are either on its way, on my garage or installed. I would like to know what you guys think about my setup and the possible problems I may encounter and what am I definitely doing wrong and need to change.
This is my mod list....
Have:
AFR 225 heads - not installed yet
MS4 cam 239/242 @.050 649/609 111lsa - not installed yet
FAST 92/92 setup - not installed yet
Melling 10296 Oil Pump - not installed yet
ARP 134-6006 8740 Rod Bolts Chevy LS1 Small Block - not installed yet
Cometic head gasket 0.035 compressed thickness- not installed yet
160 Tstat - Installed
Need:
dual springs or extreme springs, what should I go with?
7.400 Chrome Moly pushrods
LS7 Roller Lifters
LS1 LS6 Double Roller Timing Chain Set
Wideband
What do you think about, my .0028 quench area?
Thanks!!!

one thats a tight gasket. bit tightter then i would use. two i think you would be better off using a thicker gasket and milling the heads to help gain the compression you want. i would also use a stock gm ls6 oil pump and measure the pushrods and not just assume the 7.4. mine came in at 7.450 with milled heads.

Patriot Dual valve springs here.
LS6 oil pump for OEM reliablility i would guess, thats what i just installed on my car...
Also add gaskets to your list, water pump X2, timing cover, (reusing valve cover gaskets are usually fine). I'm not sure about going with new/hardend pushrods becuase your going with new heads
Otherwise i would stay with stock pushrods, I'd rather bend a pushrod than drop a valve 
Are you doing the work or dropping it off at a shop?

I would prolly go .040 on the cometics. And measure PR length. And call AFR and see that you can safely mill cause I am guessing it will close on a .040 HG. Yes I know AFR's will clear a litte more than a OEM head but it is worth a call IMHO.
Sounds like a stout setup when you get it together

hardended pushrods are needed when installing a bigger cam and heavier springs. Problem areas i can remember are remember to put some silicone at each corner of the oil pan gast where the front cover meets it, it WILL leak if you dont. after installing the cam and heads and everything, check the length of the pushrod and get a correct length dont just assume, 1) it will rod power if too long or too short, 2) wear out parts quicker since its not aligned right.
All in all sounds like a good setup, hope you are full-bolton!! Also get you a 85mm lid and MAF. And FTRA if you dont have it

We will mesure pr length and ptv, if flycutt is needed then it will be done, melling 96 is a much better pump than a stock or ported ls6, my built forged 346 engine has one and at idle oil pressure is about 285 kpa
I like quench area, it will end up about .03 but would you use thicker head gaskets?

I think that the fly cutting a of the pistons and the cometics .040 will be a must... I'm not much of a mechanic, but most likely, 2 friends that know that they are doing, and I will start doing the built in about a week.
Hopefully the car will be running by the first week of next year. I also have plans of swapping the axle and doing the rear suspension.
Thanks a lot for the comments, keep them coming...

Just curious why are you going with the AFR 225's instead of the 205's.
Your list looks very good. I agree that the minimum you should go with the head gasket is 0.040" and mill the head if you want more compression. I've asked and searched about head gaskets thinner than 0.040" and found that the piston the head clearance is already at the low with 0.040".
Depending on what you're doing a LS2 chain/guide is probably suffice and lighter than a double roller setup.
You might want to look at porting your FAST intake while it is out. If you don't want to spend money doing it then do at least some work yourself. There are several very good informative threads on here with pictures on where and how to port the FAST intakes.
On the cam you could go with a custom grind from Patrick G and/or Predator Z. Custom grinds don't cost more than anything off the shelf so I would go custom and have something spec'd/designed to fit your needs/criteria.

...About porting the FAST intake, I'll look that up, that's a great idea.

The melling is a better pump. The casting is nicer and it flows 18% more than a LS6. Stick with it.
I would prolly go .040 on the cometics. And measure PR length. And call AFR and see that you can safely mill cause I am guessing it will close on a .040 HG. Yes I know AFR's will clear a litte more than a OEM head but it is worth a call IMHO.

why do you want more volume? what will more volume do without the use of an external cooler?...that is more volume in a diff way though. pumping the same amount of oil, just more per cycle...but what would the help?

more volume is not neccesarily a good thing on these engines. id stick with a gm pump. plus i have seen issues with a couple mellings right out the box. esp with a double roller. my car has a stock pump in it and never a single issue and plenty of oil.

I'll try to take pics of the built and post them on this thread.
The one thing that keeps me worried is if I'll be able to have enough torque down low with the AFR225 big bore heads. What compression would you guys look for with this setup in order to get as much power down low as possible.

thanks a lot for the tip, we'll doble check the p/v clearance.
I wanted to be on the safe side, but I think I'll be ok with a single row chain from an LS2.

get that compression as high as u can before it becomes an issue with ptv. but try and keep it under 12:1 for pump gas. 93 octane. i ran 11.5:1 on my head/ cam motor.
