Been doing to much reading and every time I find somthing I think is good I find some one who broke it lol so at this point I'm ready to place a order but need to lock down some solid parts. Shooting for 500ish whp all motor

Current parts that WILL be used
-stock bottom end LS6
-ASP under drive balancer
-LG long tubes, Catless X pipe, Borla cat back
-AFR CNC 205's stock CC and un milled
-Fast 102
-90mm LS2 TB
-LS7 42lb injectors
-COMP 1.75 Roller rockers
-Thunder Racing 7.040 push Rods

THESE ARE THE PARTS I BEEN LOOKING AT, other options or opinions welcome!

Texas Speed Magic Stick 4 239/242 .649"/.600" 111lsa

Rollmaster LS1 Heat-Treated, Double-Roller Adjustable Timing Set (better options???)

Melling High Pressure Oil Pump, 97+ LS Engines

Texas Speed & Performance Lifters by Morel, 5290 LS Link Bar Hydraulic Roller
(want to ditch the plastic trays and these seem decent for the price??)

PAC Racing Springs RPM Series LS Beehive Dual Springs-PAC-1221X .650 lift
( AFR recommend part number AFR8019, but these are a cross over)

What head gasket and thickness are you guys running?

 

Whats the CC on those heads? Your going to need 58cc to achieve the below listed comp.

BTR Stage 3 camshaft, 5290's are a fantastic choice.

3/8 manton pushrods measure each and every intake and exhaust.

BTR Springs with Ti retainers.

You will need atleast 11.5 compression, so without fly-cutting the above listed camshaft will be about the limit.

Stock rockers for weight savings.

 

66cc is what they are, heads are going to the machine shop Monday to be cleaned up and checked out so I could have em decked then. How much needs to come off to loose 8cc? 11.5:1 still 93 octane friendly?

I'll look into that BTR camshaft. Fly cutting is possible. Already was looking into it. Dosnt seem like a very complicated process.

AFR and most everyone else told me not to use stock rockers because of the bronze guides?

 

I would talk with Tony Mamo about your valvetrain as he designed
The AFR 205s in 2004, and designed more 500 RWHP Combos
With AFR 205s than anyone else. I'm sure he will recommend Yella Terra
Roller Rockers, and the appropriate valve springs. To reach
500 RWHP with 347" and HR you need perfect valvetrain
Stability to 7200 RPM minimum! I would also speak with Kip
@ CAM MOTION, there lobe acceleration ramps are more gentle
Which promote valvetrain stability and longevity at higher RPM.
Something like 231*/235* .612" (.360 lobe X 1.7 RR)
.595" (.350 lobe X 1.7 RR) LSA 114*+3*
I would also have Tony Port your FAST 102 & TB,
Worth another 15+ RWHP. Also get a Velocity Ring to adapt the
90 MM TB to the FAST 102 inlet.
Much easier to tune with better low speed airflow and Driveability.
Just my .02.
Good Luck!

 

That velocity ring looks nice,cheap to. I'll order one of those tomorrow. I'll message tony and see what he has to say since he did design these heads and knows the 102 inside and out.. But i feal like I'll get 10 different answered from 10 different people lol I just want a solid performing package that will make good useable power and a lot of it!

 

.007" per cc when flat milling. To make the power numbers you desire you will need ~11.5.

TM would be your best choice when looking at camshafts grinds specific for your goals with the AFR cylinder heads.

I chose TFS because the came with 58cc chambers and 13.5 degree valve angles to accomplish my power expectations.

Your on the right track. Valve control, Camshaft Grind, Compression. This is where the power comes from.

 

Besides calling Tony, measure for all pushrods and don't start buying parts until you get the whole thing planned out.

 

I actually been looking around for some TFS heads. I had some gen X 225s on a 408 a few years back and that motor ran exceptionally well. The AVA will free up some PTV also correct? If I mill .056 off the heads how will the intake fit?

 

It could certainly cause a misalignment issue.....The Fast 102 gasket does a pretty good job of sealing. Tony can probably tell you before you ask the question about alignment once the heads are cut.

I've been using TFS for many moons......SBF, SBC, BBC and now LS. They flat work period.

They will aide in creating VC and allow the use of a larger cam grind.

Look up my dyno graph from a few months back. It doesn't include an updated after the Fast 92 install. That car was certainly very close to 500whp after the 92mm intake and TB.

 

Went with BTR on this one. Placed my whole order there and they hooked me up with a discount that saved me about $75 and shipped it for free. Can't beat that!!

They spec'd me a stage 4 cam kit,platinum .660 springs with Ti retainers, JohnsonSLR lifters, and 7.350 push rods. I'll have to double check pushrod length, and said if I need a different length rod to just send em back and they will send me a different length. Good people over there.

Anyways sticking with my current 205's, they should be done tomorrow at the machine shop then it's build time. If I seen 485 or so WHP that would be fine since I decided to buy a Nitrous outlet plate kit to. So that few Hp's my heads are down will get made up with some spray! lol

Pretty much updated everything I could to while I was in there, , LS2 throttle body, LS2 lifter trays and new style cam retainer plate, LS3 shorty injectors, new fuel rails, new gaskets all around, new oil pump and seals

 

POST PICS of the 205's bro!

 

I will when I pic em up tomorrow, had em glass beaded, cleaned, and Totaly freshend up.

 

Well I was looking he heads over now that there all fresh and clean and noticed a little stamp on the head that says 042 59cc. I checked the CC and sure enough there 59cc heads.. So that will get me right to the 11.0 I was wanting right? Is the 042 number the amount some machine shop previously took off ??

 

11:5:1 static compression will get it there. Cylinder head will be the main factor, Also small stuff here and there to gain those extra 3-5 Hp here and there,lighter flywheel,electric water pump, good flowing exhaust i can go on and on. You wan honestly push it up to the 11:8:1 - 12:1:1 and keep it on the pump .

 

I would think you would definitely want to check PTV clearances with those millled heads and the stage 4 cam. Also, do the heads have PM guides or Bronze? Are you running stock rockers or roller rockers?

 

There bronze guides that's why I'm kinda stuck using a roller tip rocker. The car did have stock rockers on them for a few thousand miles though from the previous owner, and the machine shop said the guides looked perfect. So who knows?? All I know is AFR and a few other people said NO No on stock rockers with bronze guides lol so it made me nervous.

I checked PTV and I got like .045 on intake and about .100 on exhaust
