tech support as in IT helpdesk, not shop tech. Maybe you knew what I meant, or maybe not.

I worked helpdesk out of college at Wyeth pharmaceuticals for 2 years 03-05, then left to go to iron mountain, was made a Team Lead after a year, and was in that role for another year and then systems admin for a year, business systems analyst for 5 years, network engineer for 1 year, network solution engineer for 7 years, solution architect for 5 years.

 

thst tracks thst the 2.130 valve would be 75ish grams then.

 

I asked about As cast heads and he said this. Do you think he means they don't have the moldings yet for the as cast?

Good news about the cnc heads, but that might annoy the companies like GPI who wanted this business from them for all customers. Most people will probably just buy the heads straight from btr and cut out the cnc companies.

Very curious as to the price. Bare heads are 899 a piece. Fully loaded and cnc probably 3k?

 

Regarding AFR the only full Chinese situation is the entire Enforcer line.....and that line doesnt hold a candle to the CNC line I designed for them which is still being sold to this day.

The difference in flow, performance, and efficiency is night and day . The Enforcer stuff is really the equivalent of new unported OEM castings in terms of flow etc. But I mean look at the price....your getting decent hardware but those are not the heads to buy if your looking for real performance.

Regarding the LS7 heads your looking for I already make them.....LOL

Seriously.....over 400 CFM (400 - 415 depending on which Stg head you purchase from me) thru a 265 cc LS7 port......that's 5 cc's smaller than an out of the box LS7 factory head (which is no slouch) but it flows close to 50 CFM more thru a slightly smaller port..

Your getting medium sized aftermarket Big block Chevy head flow on the intake side with a modest sized port delivering the "violent" type of airspeed and efficiency your searching for. These heads make a ton of power on just about everything. Start Googling results of my MMS 265 LS7 heads and there are boatloads of examples out there to look at. Just about everyone I help makes over 600 RWHP....even guys with small cams and mild builds are in the 600 - 630 range on pump gas.....more aggressive combos with larger cams and possibly flex fuel are in the 640 - 670 range with brutal midrange torque and tons of throttle response.

No need for me to chase what I have spent the last 10 years perfecting using the more readily available and much lighter weight TFS castings (The CID castings are just retarded heavy....unnecessarily heavy in my book unless your targeting 2000 HP turbo stuff that really needs that type of mass to live properly).

Whether your going with a mild build or something more aggressive with larger cams etc. my 265 LS7 head (or my 260 cc LS3 head) are just ideal for 95% of the guys reading this.....just a killer all around street strip head that fits in just about everything and is quite affordable considering the equipment I build them with and the extra TLC they get that allow them to flow as much as they do with that very conservative sized port. Air speed is every bit as important as peak CFM....arguably more important and that topic is lost on alot of shops and individuals but the sharper guys pay alot more attention to it.

I've already mostly answered your question in what I just posted above.....the difference you are really chasing is the SET UP.....the combination itself is what you need to adjust......the head choice is still the same.

Something you want to put a ton of miles on with the focus on reliability just comes down to more prudent cam selection....paying attention to the aggressiveness of the cam lobes themselves and going with something with less lift and smoother profiles the extend spring life.....paying attention to mass in the valvetrain (hollow stem intake or titanium....both option I always offer with my heads) and most importantly running roller rocker which massively reduce the sideloading and wear of the valve guides typically tripling the service life of the heads. Once again.....check on just about every Mamo package on the Net and you will see I run YT roller rockers on just about all of them (LS1, LS3, and all my LS7 stuff as well). That's another topic that I feel so many miss the boat on but there is a reason I select the parts that I do when I build and design my packages for my customers.

Bottom line....what your wanting is a piece of cake for me and I offer my customers packages like this all the time.....not everyone is looking for max effort I assure you....in fact MOST people are actually looking for builds more along the lines you just inquired about.

I suggest you just get me on the phone one day and we can discuss it in more detail

Alright guys....Im out of here....its 5 AM and I need to crawl back in my coffin.....LOL Hopefully gave a few of you some information you find helpful.

Been meaning to respond now for a few days but its the busy time of year so its a bit more challenging
