You MIGHT be able to get by with the stock injectors. I vote for the LS6 intake. Keep an eye out for some GTP injectors. they're 36# and you can usually get a set for around $100 used.

LS6 intake leaves a lot to be desired with ported 243 heads

You are right. LS6 is the best one out for a head cam car. SMH. Think before you post

You are trying to make a decision between a need and a want. If the engine's airflow demands fuel beyond the capacity of your current injectors, then you have to get new injectors. If you add an LS6 intake and it throws the fueling demands beyond the injector capacity, then you have to get new injectors.

If you can't afford the possibility of needing to buy new injectors after getting the LS6 intake, then you should leave the engine as it is and check the injector duty cycle. You also need to keep in mind that the tune needs to be adjusted with any new injector sizing.

I was not aware that a couple of mild bolt on's
would need new injectors. As mild as his setup
is, seems like the seat of the pants would appreciate LS6 intake more.

Very true. I'd imagine the guy is on a budget and anything better is definitely out of the question.
That said OP, an LS6 intake is certainly worth the cost over an LS1 piece. You get what you pay for here.

It may be possible that your setup would need bigger injectors, but they also may be sufficient for the time being. I'd go with the LS6 intake and take Mike Morris up on his very inexpensive offer. It's very possible the stock injectors may be reaching their max capability with your heads/cam setup.
I don't mean to be rude, but I think it would be wise to ignore slogo's comments here.

He is adding a Torquer V2 and ported 243s. I'm pretty positive those stock LS1 injectors are going to be taxed beyond their limit.
