Default Stroker build questions

So I have a gto with an ls2 that spun a bearing, I have a stroker kit on the way. 4" crank 4.020 -15cc dish pistons. Should be around 10.4 compression and 406ci. I have ported 243 heads and a torquer v4 cam now (231/234 .629"/.615" 111 LSA).
I 100% will be turboing the car in the next year, but I think I'm going to run N/A until then (the car has been down for a year I want to drive it soon).

I guess my questions is should I switch from my ported 243 heads/ls2 intake to LS3 heads/intake or just switch intakes or does it even matter if I'm turboing.

Second, I know i'm going to need another cam. Any suggestions for a stroker turbo cam?

This is 100% not
a daily driver and will be on e85.

Honestly, the stroker will almost be irrelevant if you're turboing it.
I'd stick with everything you currently have, cam included, and get an 80 to 88mm Borg warner clone in a 96mm turbine with a 1.32 A/R T6.
That cam is smaller than the one I'm putting in my turbo 5.3.

1. I see no reason to go with the LS3 top end if you're gonna turbo it down the line. But that's just me.

2. Get with Cam Motion regarding a turbo-cam to fit YOUR needs and your engine.

He wants boost. The LS3 top end will increase power N/A, but with boost its almost irrelevant.

That's actually a get idea. I forget that cam motion is local to me.
