A set of 243s and ls6 intake, new coils and injectors. Trying to see how many hours it would be. Ball park with all the right tools available.

 

It depends. i vacuumed the block with a wet-vac to remove coolant before pulling the heads. That saved on cleaning time. But, even so, probably took as long to clean the head bolt holes as to tear-down/reinstall everything else.

I also installed ARP studs. That said, probably had 20hrs labor in the job total. This included a cam swap.

 

Depends on your skill level. 1st time it took me two work days, second time took a little more than half that.

 

If you have all the tools and do it correctly and have everything already like gaskets, headbolts, etc. if you do depending on skill level I've done them in 5 hours with all the cleaning and scraping old gaskets off. You'll also have to do a oil change so don't forget that.

 

Give yourself a whole day.

 

I thinking about doing this as well, after reading the instructions I'm planning on 2 days

 

While I'm in there what else should I replace. I have new coil packs, injectors, ls6 intake, plugs, gaskets and oil. If so please list part number and if you got a good deal somewhere, let me know. Thanks fellas. also what gains can i expect from swapping on these parts and a new tune.

 

heads and intake i can do them in bout 4-5 hours
