as long as they are 96 and newer they are good and are true vortec heads

Yeah be sure to double check the casting numbers. The last 2 guys before I got my vortecs, said they were vortecs and they turned out being L35's.

Also be prepared to spend another $400-$500 assuming the heads are in good shape to get the manifold fabbed, heads drilled, and all new gaskets.

Check out the ports and chambers... heart shaped chambers and d ports. The L35 ports have a small semi-circular relief at the top of the port like this

Also--- check the bolt patterns :lol:

Re: Would this work?

At the time I didn't have any pictures of them all I had were the casting numbers and them swaring up and down they were vortecs. Come to find out one set came off like a '94 and one came from a '95 :roll: Luckily I was able to figure all this out before I bought them.



Does anyone know if since I swapped over to vortecs does the smaller appearing combustion chamber raise my compression any?

Also are the numbers i've read stating that vortecs flow 2 times as much as stock acurate numbers? I measure the runners on both heads it almost seemed like the LB4 heads actually had bigger runners when mic'd. I know the vortecs are taller but the LB4's are wider :dunno:

I think that your compression will go up a tad but not enough to bother yourself with.

As far as the flow goes... a large portion of it is in the flow path and not the port size.... but the vortecs have been benched to around 248 CFM , the stockers' flow just under 160 CFM IIRC

If I ever get the new long block I'm doing it in my GT as well
