The right bottom to match the top.
The right bottom to match the top. Right now i have ls6 heads and a ms4 cam for my 98 z28. I have a little extra monney so i figured what the hell ill build the whole motor while im at it. Im tring to figure out what would be a good match for the top end i have. I was thinking either an iron block 408. or stock block 383 stroker. 
Ive heard that the 408 is to big for some ported ls6 heads but i dont know.
P.S. I want to spray the motor, 150+ shot.

IMO bigger is always better. Yes those heads will work with that cam and the 408. I have a customer who took our 408 short block and put stage 1 LS6 heads on top, ms4 cam made 470/440 with an LS6 intake.
It's not that its to big, its that some heads dont flow enough to allow it to reach it's maximum

I definately prefer the 408 over the 383. We typically stock 40 short-blocks & will be running a special on them next week! If we can help you with your combo please give us a call. I'd be glad to help anyway I can!!
