Found an LT1 cam for my L03. Now, aside from the other things I a, getting for the cam, I was considering heads. Now, should I have something done to the stock ones or invest in new ones? Keep in mind I'm not Mr. moneybags and I just spent a billion dollars on Edelbrock TES headers, SLP cold air, Flowmaster, NOS, etc...so has anyone had experience with aftermarket heads THAT WERE CHEAP? What do you think of them? And..uhh...how much were they?

 

Here are a few options...
1)Vortec head kit $679.95 + machine work (.040" off the bottom)
This would be everything that you need to run the Vortec heads. kit includes assembled Vortec heads #12558060, head gaskets, head bolts, rocker arms, Edelbrock Performer intake, intake gaskets and 12 point stainless steel intake bolts.

2)Aluminum L98 heads $799.00 + intake
With this option you would still need to get a new intake manifold and an adaptor plate. You would not, however, need to get the heads machined.

There are a few other options out there, but I'll leave those for someone else...

The vortec kit is worth every penny. Best darn cast iron GM heads ever made if that says something!
I understand the "not made of money" part but you get what you pay for and the vortec heads leave NOTHING to be desired. Better flow for the street (under 3000rpm on a 350ci) than the vette heads!!!
The best part about that deal is that it comes with the intake and all the hardware.

Will vortech heads work with edelbrock tes headers? Just curious because I plan on getting them both at the same time and don't want a headache..

 

OK, I have 2 questions about the vortec kit.

1. The heads are designed for a 350, which is why we would need to mill them down .040" to keep our compression ratio the same as stock, I understand this. BUT, doesn't the 350 have a larger cylinder bore than our 305?? If this is true, which I think it is, won't there be the potential of the valves hitting something?

2. Is that intake manifold able to accept an EGR?? I need to keep my car emmissions compliant, so if it can't accept and EGR then I can't do it.

Vortec heads have 1.94"/1.50" valves, they do clear the cylinder bores. You don't run into cylinder wall clearance issues until you get bigger than that with more than .450" lift (read that on Edelbrock's Website).
I'm not sure if 2.00"/1.60" valves will clear or not, but 2.02"/1.60"s won't.
Not sure about the EGR. I don't think that Vortec heads have EGR provisions, but, I'm not certain.

I just realized that the quote above is misleading. It's from Edelbrock's website and it's refering to their cylinder heads because of the valve size.

What about the S/R torquer heads specifically designed for the 305?
