Please help with my build
Left to Right on your previous post.
ALSO,
I NEVER said "you have to run 5 and 4 won't work"
I said "IF +6-8* Exhaust Split is ideal for Cylinder Heads with
Less than 75% E/I ratio above 6500 RPM, then +5* would
Be better than +4*"
Top Tier Cathedral Heads (MMS, TFS, AFR ...) with Optimized exhaust (1 7/8" LTS & True Duals or maximal Y) perform best with +4-8* exhaust splits NA.
Ported OE Cathedrals generally need a little more exhaust duration.
"Real World"
(If that is hypothetical, why do most
LS3 specific cams have +8-12* exhaust splits?)
The comparison was between the Taunami VS MS3 on a
370" with TSP LS6 Stage 2.5 Heads.
You have a Nasty habit of putting words in people's mouths as well as
Commenting on other Vendors parts, performance & availability
and are often Wrong!

Rect ports arent cathedral so that argument isnt valid in any way. Every company is different but there are some companies that use single pattern or less than a 10 degree split on rect port cams also, spin monster comes to mind with only 2*.
Often wrong how? Having a differing professional opinion and actual results or experience doesnt mean i am wrong or they are wrong either. There is more than one way to get the job done obviously.
The availability part i am right on though. Evem mr mamo said so. You wait at least 4 weeks. Its posted numerous times. The performance...you can make just as much for less...still right there also. That wasnt just me stating tha fact also.
The only vendor I "attacked" was clear and it was only 1.
I can agree to disagree but no need to put words in my mouth either just because you are sore.

OP, I recommend you contacting Pat G. He have made over 500rwhp on 6.0 motors using cathedral heads such as PRC 227, AFR 230, TFS 225 just to name a few. And the cams mainly be speced upper 230s on the intake and 240s on the exhaust.

We have some stock pistons that have a slightly reduced CH and sit at deck not .009 - .012 out so they gain quite a bit of extra ptv also. $300 for pistons and rings. Hard anodized top also. Floating pin. Flat top no valve relief.
Yes the tsunami will have slightly better ptv like they said. That being said, make sure you have an adj timing set and a good pushrod length checker to verify all that. And maybe some machinists clay and checker springs.

How are you trying to make 500 rwhp? They will handle quite a bit, we have guys throwing 150-200 shot of nitrous at em already and a few with Maggies. Its all in the tune, fuel quality, and ring gap.
on a serious note.
I would call or contact Cam Motion, Pat G, Mike Jones and Ed Curtis for help on cam selection for your project if max hp is your goal.
Regarding TSP's conflicting cam information, I would ask to speak to TSP's lead tech on cam testing. I can't recall his name but he's usually at LSfest with TSP cam display. He's knowledgeable and would be best choice at TSP to get the conflicting information resolved.
WS6 STORE is also pretty sharp with this stuff too, provided they have all the relevant details.

Obviously others in this thread are not.
Debating internally whether to continue posting as I am having
Whole posts deleted.
Nice censorship/favoritism and protectionism Going on.
Expected more from residents of Texas.
There is always more than one way to build a nice combo. We are both very passionate in our views. Nothing wrong with that. Some days are better than others.

To me the best BANG FOR THE BUCK would go towards some TFS 220 as cast heads. Cheapest place I've seen to get them from is Brian Tooley Racing unless someone on here can beat his price on those heads.
Our pricing is VERY competitive with everyone else out there.
Remember...you can get tfs heads bare with valves also so they will show a lower price. We offer pm guide "upgrades" as well.

1. The TFS 220 is a great head - does even better in the hands of a great port wizard, and by all rights, it should outperform the AFR 205.
2. PatG did it on a Fast90. That STILL impresses me
3. Cam events were 237-ish x 245-ish.
4. I think he used a Y-pipe, not an X pipe
5. He was using XER and LSL lobes, and we have sort of moved on past them also.
Really we are in a great age of parts availability right now, even for the cathedral platform, and it has made this hobby lots of fun. but even with the better parts out there for us, it still takes quite a lot of attention to detail to punch that magic 500 number...
I still like lsl lobes and have used some xer lobes on ls7 heads. They seem to like them.
There are newer designs now but so many from earlier that werent used also.
Having the ability to design our own helps also.
Every cam manuf has had to step up their game lately.

Im debating on switching heads to maximize my setup and get it to the 500 mark just want to make sure the pistons you sell would hold up, for na purposes what to you guys recommend for ring gap with those pistons?
