Advice on 241 head build
Hey how’s it going guys. I have a Ls1 z06 & finally decided to get a cam kit from Texas speed. I need some advice on what else I would need for this aside from what’s included in the kit. Hopefully you guys can point me in the right direction.
cam kit
- Tsp bald eagle cam 277/234, .600/600 111LSA
- Tsp 7.40 chromoly pushrod
- Tsp polished .600 dual valve spring kit w/ integrated seat/seal
- Prc titanium retainers
- GM high performance LS oil pump, wet sump
- wet sump balancer pulley, LS front crank seal, water pump gasket, & timing cover gasket
car is basically stock besides kook headers, catted x pipe, & corsa axle back

My advice is made since you sound to be technically proficient and comfortable doing the work.
One thing I now mention is replacing the lifters while you're in there since my last LS6 had one fail and take the block. Relatively cheap insurance.
Stock rockers go a loooong way, but the bearings can fail and many opt to replace the needle bearings with bushings by Straub or Che. Do not use comp.
I don't recall while writing this if you mentioned a new timing chain was ordered or not? With all this work, absolutely do.
Why not also flush all coolant and get a new pump while it's off?

The 241s are going to limit how effective the cam is. Every document I've ever seen indicates all Z06's came with 243s. If you have 241s it raises a whole slew of questions. Since you're going with a good cam, limiting it with the heads is a bad idea -- unless you took the 241 flow characteristics in mind when doing the cam selection?

They say pictures are worth a thousand words. Do your heads actually have 241 stamped on them?

Seems odd. I didn’t think the Zs had 241s either. If that’s what you’ve got I’d opt to swap the heads. A set of ported 243s would make a huge difference. The 241s will always hold you back and it’s a PITA to pull the heads again later. Upgraded trunnions if your going to run stock rockers. Timing chain and a harmonic balancer. It really depends on what you want to possibly change later. When I did my build I knew I didn’t want to revisit something I removed and didn’t replace later on. Most people are probably different and wouldn’t just replace a good part. I didn’t want to stress old parts with all the extra HP and wait for them to break.
I also wouldn’t just throw those push rods in without checking for correct length.

Run whatcha got and enjoy it, I say. How limited will you be for 20 hp max?
If you ever did do heads, wait until your got an ARP stud kit.
And wait until you have a blower cam. Because that will be your next stop even if you don't know it yet.
