241 head on 408ci
as the title say, i got a lq4 6.0l that im getting it bored 0.030 over to make a 6.2l (408ci).... i was thinking of using some 241 heads to raise the compression. Is the 241 heads gonna give problems or should i use the 317????

6.0l - 364ci
6.1l - 370ci (6.0l bored .030 over, that is what you will have..)
6.2l - 377ci (.065 Bore, stock L92/LS3)
6.7l - 408ci (.030 Bore, 4.000 Stroke Crank)
As far as the Heads, I would go with a set of 317's or 243's like mentioned..you will choke it with a set of 241's, unless they are ported.

If you already have the 241s port them or run them the way they are and save up for a set of AFRs or Trickflows
That's what I'm doing, running my original 241s ported/ milled on my 404 til probably next year when I can get a good set of heads
