Ron and Phil are great guys to work with.........


and their heads are automotive ****.

 

I agree, I wouldn't go anywhere else but AI too.

 

Called talked to both LE and AI after you compare what you get for your money. I'm going to go with LE. With AI you get 185cc heads and LE LE1 195cc. IMO better bang for the money.But eather way you go it's going to be money well spent.

 

You really believe more material removal directly equals a better product?

 

Not much to say to that. I guess thats why people always talk about smaller more efficient ports.

 

you might want to do some more research.

 

I love how there is a gross misunderstanding of port volume and port efficency. That's bunk. We are talking about Cross Sectional Area that the port needs and port geometry from the port opening to the venturi. You want the air to increase in speed to the valve, so if the opening of the port or "pushrod pinch" is smaller than the venturi it speeds up and slows down on the way to the port. NOT GOOD! If the port opening is larger than the venturi then you are headed in the right direction.

Ever wonder why GM moved from the LT1->LT4->LS1->LS6->L92 heads all on a 5.7-6.0L motor? That's a HUGE jump in cross sectional area from the LT1 to the L92. The LT1 has a average cross sectional area of 1.88 sq in, the L92 is in the area of 3.4 sq in. Almost a 100% increase! The reason why is even though the air only uses around 30% of the port, if you fill in the other areas of the port that are not being used the motor does not make more power, GM engineers and a lot of smart head porters understand this, even if they seem to be stumbling across it by offering larger and larger port designs. It's due to local air speeds and intake pulse tuning, which is a whole different concept from average velocity and the thought (a bad one at that) that smaller ports are better because the velocity is higher.

lloyd elliott. great customer service. even 5 months after purchase. i talked to both several times before i purchased.

 

Yes, like they fear too many people going to AI and RESULTS overpowering a good marketing plan.

Some people understand the difference between walking the walk and talking the walk . A lot of people need to mistake the two for years before they learn the difference.

 

Cant compare the two but can say the Ai 190s are really nice. I had an issue with one of the heads and they sent me a prepaid ups stamp to overnight the head back to them. They checked the problem, fixed it, then shipped it back pretty quick. I doubt you will be disappointed with either but I dont regret going with Ai at all.

 

Thats a funny post... it all the usual players chiming in...

Next thing your gonna say is AFR heads suck ... this stuff is predictable.

Instead of bashing LE stuff, you should be thanking him. AI was overpriced and due to Lloyd, they brought down their price which allows more poeple to buy their heads. Ron and Phil should be thanking Lloyd

Also, Ai is lucky that this site allows Threads about non paying/supporting vendors. If this was LS1tech.com these posts would be deleted or locked.

 

I guess gaining 4mph in the 1/4 with a cam very similar to my old one in size doesn't count as walking the walk?

 

Are we starting the non-paying advertising bickering now? How many BRE cam threads have we seen?

 

What in the hell does your cam swap got to do with experience with Ai and their cylinder head services?

 

What the hell does bashing LE/BRE stuff have to do with AI heads/cam packages?
