Cast iron 15 degree heads??

Hello all,
this maybe a crazy one... but I am looking for info on a 15 degree - ls6 style head to use on a iron gen3 block. Our local track has a few very few restrictions on engines, except it must be all cast iron, (heads and engine).
So i am looking at all options, there is much advantage to 15 v. 23 that it sparked my interest. don't get me wrong, i love the big ol' rompy (1000 rpm idle 6in. vac.) engines that i have now, but i want to try some of newer technology.

Thanks for reading...

Same rules we have, I believe one or two years of the 6.0 truck engine was all iron. should make good power and live with the way the bottom end is set up.Check 99-01 trucks I think.

Correct me if I'm wrong but I believe all regular production Gen III/IV engines have 15 degree valve angles. And I think the new LS7 engines have a either a 12 or 13 degree design. I'm pretty sure they left the 23 degree heads behind when they went to the new engines.

And yes, there were a couple years where the pickups used iron heads. I know my '00 6.0 has iron heads on it and possibly the '01s too. I'm not exactly sure when they started going to aluminum.

thanks ahead rippin ron,
That would be a great help.
Not many of those trucks make it to the u-pull its yet.

I know that the new trucks lq9 (and lq4 i think) 6.0 engines are cast blocks with aluminum 15 degree heads.
I think the first 6.0 truck engines would be the iron ones.

Thanks, Brian

Psycho, the 99-00 6.0s for sure have iron heads.

What engine do you have now that you want the heads for?

As of yet, i do not have any. That will change soon, when we can get our hands on a couple of gen iii cast truck blocks. I am just stepping into the newer blocks and looking for info. I have already learned a bunch since starting this thread. Can't wait to try em on the track.
