And it drives really amazing. Just like stock.

We've got a special going on for all LS engines for the head install. We will send out our cores to get ported for you so you have minimal downtime - just the time it takes to install and tune. This does not apply to the LS7 (as we don't have a set of those heads). We have LS1, LS2, and LS6 heads in stock ready to be sent out.

You can combine this special with a cam install and save some pretty good labor there!

Many guys do - some built by highly experienced shops tend to do it out of the gate, while others end up working at it to identify areas of their setup they can refine to get things up to potential. Either way, the potential is there.

I'm sure it drives quite well, I try and stick with cams in this size range since they lope a bit, but with proper calibration have essentially stock manners. That is especially the case when guys retain OE clutches.

If we schedule work ahead of time knowing when heads will be delivered, especially if it is machine work only, then I can typically turn them around in far less time than normal.

Thanks for your hard work on it!

I like small cams that put up big numbers. It's all win.
