I'm hoping you're not just taking a torch to them. If you can find out the alloy/grade used for the rods you can look up (or should be able to locate) correct heat treatment steps to get increased hardness without making it brittle.

I know what im doing lol. Theyre made of 1019 so theyre barely hardenable but it will still work. I just dont think the oven in the machine shop will be able to austinetize the steel... We will see. Otherwise yes i will flame harden them haha

Find out if the chemistry department has a muffle furnace, that will get you to temps for austinetize the steel and you'll be able to control the cooling to ensure correct formation of the steel

Cryo is real and it allows for a more complete transformation into martensite but this has to be during the initial cooling process of the heat treatment.
I think some of that debate is just random ass cryo treatment. It doesn't do **** if you just cryo treat it from room temp. from looking at fmsr and I noticed they have the option to cryo treat everything but it wouldn't do anything for the **** that they sell (if they even sell anything) because they'd have to make it a full heat treatment process.

Ported exhaust mani? Cool.
Thanks to ARM for the idea on this.
Little Bit of pitting on one lobe of the new engine...Hopefully no problems here
Motor is ready to go in, just waiting on a couple small things like gaskets and bolts. Decided to use the 2.4 head so we will see how that goes. All of my 2.2 headwork will be saved for another project. Cleaned out all the ports and the intake and TB, also powercoated the VC and swapped over the clutch and thermostat housing.

so at this point im kinda confused. the pontiac g6 used the e37 ecu with the vvt 2.4 and the part number between the pontiac cam and the cobalt/hhr cam is the same. but the cobalt/hhr use the e67 ecu. So why is the reluctor clocked differently??
