I sent mine to Texas Speed. Very reputable.

Texas Speed the most affordable and very sopod results.

Total Engine Airflow for the meanest but they are not the cheapest.

TSP and Katech have the best prices. Some would argue that Advance Induction is worth the extra money. I like my TSP stage 1 243. Work great on the street.

Advanced Inductions.

I had a set of 243s i sent for there 232cc porting. Badest stock ported heads ive ran. Made awesome power on my old built 6.0 setup!

West Coast Cylinder Heads.

But these days just about every one who CNC ports cylinders does a great job.

Advanced induction is good but they customer service isnt good as far as communication. You might get a reply or you may not get one at all.

I never did get a reply at all and I sent that message in October! Gregg @ TEA replied within a day and answered all my questions. Im going TEA, TSP or Possibly Thompson Motorsports.

TSP, PRC, livernois, FED. All good. Pay up for the valve job. More gains in the valve job and chamber blending than in the porting

I might have said this in another thread, but I believe the valve job and bowl blend is where TSP does most of their work, as there is VERY little removed from the port itself. This might explain why their heads are very efficient almost throughout the lift range.

Philosophy - durability matters in daily drivers & street cars in my opinion& experience. I always havexto build with the intention of the engine being capable of going 100,000 + miles with proper maintenance i.e. new valve springs, seals, and hardware. That costs more upfront and less later on.

All sorts of performance increasing but durability reducing practices can be done. Raising the port floor aggressively will get more air flow but increase risk of cracks later developing. Hogging out the bowl area to get material away from the valve guides can improve flow - until the material cracks and guides fall out Typically using more than a 2.04 intake valve on a stock valve seat has less durability in most applications. There are machining techniques commonly used in road race oriented heads that improve durability.

I know from first-hand experience these three companies do quality work that makes hp and lives I'm sure there are others out there too.

TEA aka Total Engine Airflow - should always be a prime contender for posting 243/799 castings. They have many CNC programs to meet you needs. The hp potential is well proven. In superbly sorted and optimized 346 LS1's ~ 520 + whp has been made. The build quality is outstanding and significantly better than most competition in my experience and opinion. I ran a set of TEA Stage 2 5.3 706 heads for 15 years and 132,000+ miles. Springs and hardware replaced as normal maintenance. I also have a set of TEA Stage 2.5 LS6's that Tool hand finished that treasurer sweet on my 91 RS. In my opinion TEA uses good quality hardware. The titanium retainers are better grade material than commonly used these days according to one independent cylinder head shop. The down side is cast is more but in gets what they pay for in my experience.

Land Speed Cylinder Heads - Brett Land (Katech cylinder head development during C5R heyday) & Jim Stewart (Indy racing, Cosworth etc) a small shop that excels at customized head development and outstanding CNC'd heads. About a half dozen well know speed shops have heads done by LSCH heads. Attention detail is outstanding, quality work, quality parts, fair pricing, outstanding power are all trade marks of LSCH. Want 330-335 cfm of flow out of a CNC'd 243/799 casting, Land Speed can do it. LSCH did my latest set of 799's. Best know by GTO/G8 owners and road racers.

Reher-Morrison - Darin Morgan's work speaks for itself. Well know and well proven.



Advance Induction - great reputation for the product. I've looked at AI and considered AI probably a half-dozen times for my variety of projects over the last 15 years. I never get past AI erected communication barriers to actually do business.

You not the only one that says that advanced induction. I can promise you that. I just dont understand how someone runs a business without communication.

TSP must remove something when porting cause the runner is about 225 cc.

FED did a really good job on mine with a FAST turnaround!

The runner INCLUDES the bowl area where most of the material is removed.
