fast burn vs vortec heads

ok, i was looking at heads for the v8 when i drop it in (4 years down the road, gotta start saving), and it seems like the fast burn's are better then vortecs. GMPP has a ZZ383 i was looking at that seems really really nice, and would work prefectly with what ill do with it, but what are the major differences in vortec and fast burn heads?

The Vortec heads are more new school with their bowls in how they maximize the air and fuel, where the Fast Burn heads are more of an old school design that relies on larger valves to force more fuel in. The Vortec heads in stock trim can only accomodate about a .500 lift cam, so if you are thinking about a big cam and more modifications down the road, you might want to consider the Fast Burn heads because their springs can hold up to a .550 (I believe) lift cam stock. Also, the Vortec heads requires a special intake manifold that's more expensive than the standard head bolt pattern intakes.

Or, you could just spend the money now and buy a set of Dart heads and never have to worry about anything !!

Just my $.02

um...i doubt it. the specs are totally different, the fast burn engine has more power, and if they were the same why would they have en engine with fast burn heads, and an engine with vortec heads?

fast burn heads are the aluminum version of the vortec head. However, the fastburns are junk!!!! They flow a lot less out of the box than vortecs. even with machine work and new springs, you can have a good set of heads for less that $1000. I believe pro line sells vortec heads that can accomodate more lift. Also, Comp now makes a ls1 style beehive spring for vortecs that will allow a higher lift without having to have the seats cut.

any time I've head any one refer to a head as a fast burn head, they've been talking about the aluminum vortecs. This is coming from parts guys at a chevy dealership

http://www.goautocenter.com/cylinder_heads.htm
3rd one down "vortec intake"?

the fast burns are vortecs, trust me, they're just aluminum. Redesigned a little, but none the less, they're vortecs. That other motor has more cam and a roller valve train, not just different heads.

so the ZZ383 is still the better engine right? i was looking at a 385, but the hp and tq numbers for the 383 are better. i wish i could drop a 572 ramjet, but thats not going to happen.

man if you put that 572 ramjet in that zr2 and stuck some drag slicks on the back i bet that thing would do a wheelie! GM has alot of nice crate engines, too bad i dont have enough money for one. plus another problem i run into is 99% of them are for carbureted setups and you would hafta switch over some stuff for FI and the engine itself is already expensive enough.

it all depends on how much money you want to spend. The better motor generally cost more money

yeah, when i get the ZZ383 its going to FI, carb'd setups dont work too well when ur wheeling (off-camber, sitting sideways, ect doesnt make fuel flow right in them), i was also thinking about a big-block merlin....but thats too much work lol
