I installed my 224/230 about a year ago with the idea in mind that is would perform well with stock head (upgraded valvetrain) and that it could benefit from some head work. What would be the best option for head work. LE1..LE2? Also what kind of hp numbers and track times could i achieve. Thanks

 

If you have the money, I would try to get the best heads possible, the LE2 set.

 

I agree i'd go with the best heads I could afford. You might take a look at www.advancedinduction.com. Phil and Ron are awesome and will take care of your needs and have awesome customer service.

 

I'de look into the LE2 heads, call or email Lloyd and he'll point you in the right direction.

 

lloyd or advanced are good. pick your poison.
i would personally go with www.advancedinduction.com .
cnc porting is the best way to go, it if its done right.

 

You have it backwards. Show me a serious top level racing head that is CNC'd in prostock, nascar, ect...

 

Come on, now you're going to start an Ai vs LE battle.

 

Ditto's on the best heads you can afford.

 

I've had the 224/230 cam for the past 3 or so years, just rebuilt the motor and had Lloyd work his LE2 magic on the heads at the same time. I only got the chance to run it around once in January, waiting for more of the snow to melt and some warm days to get the car back out and really see what it can do. It felt good but have not had a chance to see what the combo can really do. I was advised by Lloyd to go with a bigger set of 30# SVO injectors, I picked up a used set and just waiting spring to try them out..

 

The majority of NASCAR heads and intakes are CNCed as of late FYI.

 

Negative, hes the one making BS claims.

 

thanks for the replys. Any ballpark hp estimates for le2 heads and my 224/230 cam?

What do you guy mean by "best". Biggest? I always thought that the relationship between heads and cam are really important and simply adding flow won't necassarily add hp. I mean i know adding flow will add hp but there has to be a point where things just don't get any better. Whats the theory behind it? (sorry i'm sure this is a REALLY big question so reading reccomendations will be appreciated)

Also i noticed loyd uses comp bee hive valve springs on his LE2 heads, i have bee hive valve springs on my stock heads(>2000mi). can i simply reuse the once i have and send them to loyd for a discount?

 

Yep, I sent him my heads with 918's with 1000 miles on him and he's just re-using them.

 

You’ve apparently been mis-informed. All top level racing heads (Nascar, ProStock, Top Fuel etc.) are CNC ported. If you’d seen the head castings you would quickly understand that teams would not be able to produce enough cylinder heads with an army of porters. They don’t start off anything like normal heads we are used to. How many top level guys are there around the country for every team that needs hundreds or even thousands of heads per year?


When I was down in Charlotte I took a quick ride out to pick up my 200’s at Ai & they let me take a few phone pics of some prostock heads. They hosted the best one, it's a 2” or 2.080” valve stuck down inside one of the giant ports. The valve would actually go all the way THROUGH the port & out the other end. The raw ports start out a little larger in diameter than a coin. Even if it were possible for one pro to work 24/7 they’d never supply enough heads to a top team. That still doesn’t touch the fact that there is no way a human, no matter how good you want to believe they are, is going to accurately duplicate a port as well as a machine. I like the fact that the machine doesn’t get tired or decide it doesn’t want to do as good a job for me. I know people claim who ever their favorite is is as consistent as a machine, but I think most people are smarter than that.



It’s sad so many people base a really expensive decision on what they read on here when half of the time the advice is totally wrong.

Here is the pic I took.

It makes sense that pro level heads these days are CNCd, however Im willing to bet that most of them have a little bit of custom touching up afterwords. Maybe not as I have no evidence to prove this but would just make sense to me..
