Default questions about heads

so i am planning on a build using a 98 block. will any of the later center bolt heads bolt right on. mainly a 6.0 liter head? also can you use the fast 90/90 set up with a 6.0 liter head or are the intake ports diffrent

cliffs:
using a 98 ls1 block
6.0 liter heads
fast 90/90 intake

will this all work togeather. i only ask becasue i have been told the 98 heads use different headbolts than the 99 and later. i will not be using 98 heads on this 98 block. all info would be greatly appreciated

Yes you can use the later style heads on your block with no problems, just use head gaskets for the later style as well, I think the 1998 gaskets are slightly different. The 6.0 litre heads will work too!
