Vortec heads and L-98 headers
Has anyone here tried using the cast iron, straight plug Vortec heads with the stock L-98 headers? I'm wondering if the plug boots will clear or if they will just burn.
The heads seem like a great choice for a street car when paired with the matching Edelbrock base for the TPI. Inexpensive and great performance. Yes, I realize it's a small weight penalty, but I don't think I'd ever notice it.

I was considering a vortec head swap on my 85. I didn't think about the headers.
I also didn't know about the Edelbrock manifold. I was looking at the SD manifold and heads. Links below.
It looks like a pretty good swap and bumps power to about the same as an LT1 car.

Keep us posted if you make this mod. I would like to learn more about it too.

From what I understand the SD manifold is the Edelbrock manifold without the Edelbock name. I need to check with them to make sure of that. Jegs has the heads for 612 shipped for the pair which is a great price!
I'd also want to do a set of 1.6 rockers on the stock cam at the same time and a set of AS&M big tube runners.

The one thing I do remember for sure is the center bolts for the intake are at a different angle than the stock heads. One is angled and one isn't, but I don't remember which is which.

I just spoke to SD and they confirmed that the base is their design and Edelbrock makes it for them.

The guy from SD told me that they dsesigned it, Edelbrock produces it and also sells it under their own label (Edelbrock). From the pictures it appears the only difference is the lack of Edelbrock logos. In my case (being in Kalifornia), I'm thinking that would be a good thing as far as smog stuff goes. The less there is to attract attention the better.

It sounds like a good upgrade.
Have you thought about tuning? I suspect that with that much change in airflow with the new heads, intake and rockers it will be outside of the stock prom.
Keep us posted if you make the change. Let us know what you think about how much improvement and if you have any issues with installation.

Will do, but if I go this route it will be a while. Too many other things going on right now.
