ETec 200, FastBurn, or Large Port Vortec for my 400?

Well all this time I've been planning a "budget" rebuild for my 400 small block, that keeps getting less and less budget Now, I'm thinking about moving out of the current Vortec 906 heads. Here's the combo so far:

-400 SBC, .040" over
New balanced rotating assembly, Eagle crank & rods, KB pistons 22cc dish makes 9.8:1 w/ --64cc heads
-Lunati Hydraulic Roller BareBones 10021, 232/242 @ .050, .507 lift w/1.5 rockers (could go 1.6 if I want)
-TH350 with 3000 stall converter
-12 bolt rear with 4.10 gears posi

So, been doing a little comparsion shopping, the Edelbrock seem to claim themsleves champs of the group, but I'm not sure what to think. At this point, I don't really care about a small cost difference, just want the most out of my new combo. Considering the following heads:

1) Large port vortecs iron (not the stock vortec but the GMPP 206cc runner). 65/66 cc chambers, puts compression at about 9.7:1 depending on final chamber vol. $1000/set
2) Fast Burn GM aluminum (200cc runner). 62cc chambers (advertised), should get almost 10:1 with thse $1280/set
3) Edelbrock ETec 200 cc aluminum, 64cc chambers, should be 9.8:1 with these $1100/set (if they have them in stock, if not $1200/set)
4) Also, I'm seeing a 225cc large port Vortec in the GM catalog, PN 25534446. Says it flows 281 @.600 lift, 65cc chambers, $1000/set. Is this really different than #1?
4) Other, please suggest? I've got an almost brand new AirGap Vortec intake, so I'd like to stick with this config, but YEAH, I CAN change this if I want to...

Also, anybody know of better place to get better prices on any of these heads? I live in Lubbock and can deal locally with Scoggin Dickey, but have to pay sales tax so the shipping cost savings gets spent that way.

Thanks in advance!

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

I have Victor Jr 64cc's on my 377 (400 block) and love them. They have the 215cc runners and 2.08 int & 1.60 exh valves. I got them without springs so I could use the springs made for the cam. They use standard intake manifolds which are plenty cheap, even with victor intakes. Just another possiblility.

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

For iron heads its hard to beat the rhs heads ..... and if your gonna spend 1200.00 bucks , look into the rhs ,or afr aluminum .

To be honest i dont know much about the large vortec stuff , But 280 cfm @ .600 lift is competitive !!!

I dont think its a bad rep, but alot of people expecting more out of them than they should, bad machine work etc... Heck I have boaters using them in 600hp engines who swear by them especially while on a budget. We probably go through about 300-400 sets a year in our performance line and have not had one problem using them in apps up to about 500hp.

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

hey guys i think he is looking at vortec style heads because he has a vortec style intake allready. because he says hes movin out of his 906s. id do either of the large port vortecs. go with the larger ones if you decide you want to do upgrades later and the smaller ones if you think you will stick with this combo or somthing similar

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

Yeah, kind of what Matt said, I could change intakes if there was a similarly priced head that would make a big performance difference, but to go to AFR's is going to be $250+ over what I'm looking at, plus changing intakes, just seems like it adds up to close to $500 difference for little performance difference.

I'm kind of torn between the Etec 200's and the large port Vortecs right now....

Also, as one more update, the Etecs are going to run me $1200 for a set, the large port Vortec (iron) are going to come in at about $985.

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

I know you have the intake, but it can be sold. This seems to be a great recipe for for a cheap 400 build and easy on parts valvetrain. http://www.chevyhiperformance.com/te...ild/index.html I think the best part is the 87 octane.

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

Compared to this build http://www.superchevy.com/technical/...m05/index.html This has more cubes, a roller cam, more compression, I know for me its worht the 250-300 bills over E-Tec heads. That being said if you don't have the few extra for the AFR 180, the E-Tec200 would be my choice.

Re: ETec 200, FastBurn, or Large Port Vortec for my 400?

Either 3 heads they will be within a few horsepower within each other. The only question you have for yourself do you want cast iron or aluminum. The Fastburn only yeild 530 lift if left stock so be careful with the 1.6 rockers.
