im building a 355, and i was gonna get vortec heads but i found a great deal on some camel hump heads, which head flows better?
im gonna run an xe274 cam with hopefully around 10-10.5 compression. which head would be better?

also, anyone running camel humps, whats your combo and what kind of HP could i be capeable of?

The Vortecs are the way to go as they flow better and also they come induction harden exhaust seats and combustion chamber and the intake port design is far superior over the old camel humps. The Vortecs have bolt holes for your power steering etc.

The Vortec's are awesome ...

Just be careful, I didn't look up your cam specs ... but I think it is beyond what a "stock" Vortec will do.

Do some research, and possibly buy the Vortecs that are drilled for older intakes and have .550" lift capabilities.

Thanks, Neal

Between the two heads, the Vortecs hands down but standard Vortecs that are redrilled for early intakes are not a real good idea with most intakes.
This has been done in some circle track classes that don't allow the Vortecs but the Vortec port is about .100" higher than the earlier heads so the intakes don't fit real well & in some cases won't work at all.

On the new double drilled BowTie Vortecs, P/N 25534371 you might want to read this post that Carl from CNC Blocks left a while back regarding some pretty serious problems. (thanks again Carl)

By the time you pay to have the vortec's made to work for you, you could have bought a set of Iron Eagles or some other brand.

Better, imho b/c the S/R's still have like a more "squared-off" shaped smog chamber..

I read that the Vortec 200's are more like 205's or so... AND the only thing I see wrong with them is that GM won't mass produce them so that their price drops to about what the regular Vortec's are nowadays..

I bet if they would, GM would pretty much corner the market on hi-po street heads!!!!!!!!

As for a cheap regular Vortec option, pick up a cheap Powerhouse Vortec intake and run a low lift circle-track cam, (about .440" to say .450" lift), in your motor after switching to no more then a set of good old Z- springs, (-142's)..

Pin the studs AND no, (or minimal), machining at all!!!!

Talk about cheap "shade-tree" and I bet the sucker will still run like a "scalded dog"...

:eek:
I've got $475 into my Vortecs...including cleaning, surfacing, fresh valve job, guide bosses machined, 3/8" screw-in studs, Comp 981 springs, new Comp retainers & locks, guided factory rockers, and painted.
Ready to install.

The cost is high if you have to buy a new intake, valve covers, etc. If you are going to buy that stuff anyway, it doesn't really matter.
for example: From summit: Vortech heads machined for .550 lift and screw in studs - $740 Edelbrock performer RPM intake - $176 valve covers - $100 for center bolt covers or adapters. Heads are still 1.94 intake valves and $1016 so far ? Iron eagles with 1.94's $784, or 2.02's $970. See my point ? Sure ... you can find good deals on anything !

Actually, in my case, I'm converting the top end and valve train components of a stock 350 2 bbl.
Had to purchase an intake, valve covers, etc. anyhow. Planned on a Vortec conversion from the beginning.
Vortec package still came out cheaper for me AND with a better performance potential.
And, this is my 3rd Vortec headed motor project. :cool:

I'd be interested in a website or phone # for that Tri-City place. Every place around here either doesn't have any Vortec cores or they want $300 for them :eek: and that was "greasy and need of a rebuild".
