Well I've been thinking (yes I know-wife says men should not do that. it's not natural) and was contemplating getting a set of vortec iron heads and the scoggin's -dickey TPI manifold with the EGR provision instead of spending $900 on corbeau seats. But scoggins-dickey says you need to get the exahust gas feed externally instead of from the crossover port in the heads.

I've seen a few posts on TGO about this, but no close ups of where they got the exhaust gas feed. I've got the coated 2055's and don't really want to weld on them and screw up the coating, nor have to remove the headers to accomplish this.

Anyway, any thoughts on this would be appreciated. Power over comfort any time huh Mike Wink

And no bottles for me thank you very much!! All motor Cool

I'm too old for "baby bottles", blue, red, or otherwise Razz

Havn't seen anyone do this.

Another thing you can do, is the diverter valve on the A.I.R. tubes... un screw it, and plumb a T between the valve and the header. Run that extra port to the External EGR port on the SDPC TPI manifold.

I found other ways of spending $1000. Yes $1000. Intake + Heads (And you want the upgraded heads, not the oem-ers), plus the EGR flange/plumbing, gaskets, and the TIME it takes to remove that damn tpi.

External EGR

instead of hitting the header directly like that, reroute with a T as I mentioned.

Well thanks for the info. For now it's in the idea stage. I'm not sure which heads to go with. Paul, you mentioned do not get the stock heads. Why not?

And if I do physically get all of this to bolt up and work, then there will be chip tuning issues which I can't do. So, am hoping Glenn briefs me on the wb sensor and the other gadjet he mentioned.

Well, at first I was thinking Vortec stockers have weak springs which they do, but would be fine with your Peanut cam. The stockers have press in studs. I don't know if you remember my experiance with press in studs with a MILD lift.... but yeah pulled a couple! Remember making that tap block? Yeah, broke the stud boss off, head ruined. The L31 heads have better springs, and screw in studs.

Are the stock vortec springs even good enough for a roller cam?

I can tell you right now, CHANGE THE CAM if you put those heads/intake on.

Well now the plot thickens with a new cam and springs. And the money goes up more, and the chip tuning issues get larger. The chip issues are the biggest stumbling block for me. I agree when doing the head change a cam would be the logical thing to do, but then will the car even run with all those changes on the chip I have now? I have to drive this car to work, so it can't be down for very long. The milage in my pickup just kills me. So if I do this I have to plan carefully, very carefully

Ok, but with all those new parts, there really won't be much of a gain without chip tuning will there?

If I can plan this around a trip of Glenns down here then it might be doable if it can happen in one or two days at most with weeks of prior notice. But to put all that money in the car for parts and not have any improvment for all the work and money would not be smart. So that's why I'm asking all these dumb questions now of you and everyone else here. I want to have a complete plan and budget before starting.

Which heads are better than the stock vortecs?

Anyway, are there better heads available that use a stock TPI manifold that compare with the power gain of the vortecs?

Twilightoptics · Posted: Tue Oct 26, 2004 9:23 pm Post subject:

The vortec chambers are great. Flow is pretty damn good. The problem I see, is you might start getting into overkill on a 305 in the tpi world. That's something you'd have to research and maybe weed through on tgo or something. Maybe B will chime in.

Well my idea was that heads make power, so I could add heads and a cam, then later upgrade to different runners, or maybe a different intake using my stock throttle body. A mini ram/stealth ram maybe?

If I can do heads and a cam and keep my stock intake, I'd have a good starting point for an upgraded intake swap later on.

How about one of those little superchargers? Like Paxton or something. Leave the engine alone and just force the air into it. Could be an economical choice in the long run too by the time you add up the heads, cam, diferant intake, and all of that stuff down the road.

vortec heads are fine with roller cams....every vortec motor was a roller motor,hence equipped with roller springs.

comp beehive springs work excellent in the vortec heads,and allow upwards of .550 lift capability,and wont float the valves if you rev the piss out of it.

get a machine shop to drill/tap for screw in studs,and your set to go. if your starting from scratch,you really cant beat vortecs for the $$

btw,rodney,what is a little supercharger? Laughing

look on ebay for vortec heads,i got mine brand new for 510 to my door,and another 170 for a polished airgap intake,i still happen to have my vortec heads
