I just recently bought a pair of 317 heads of flee bay I was wondering is there anything that I might need to have these heads work with my current setup. i will be going forced induction so I am not worried about flow on these heads like bumping up compression. As far as my ignition coils do I need to purchase the brackets???? Also what gasket do I use the stock 6.0 gasket or can I go ls9 gasket?? I will be running ARP studs to not blow head gaskets. Thanks in advance....

You need to use a gasket that works with the bigger of the two between engine and heads.
Of what i have seen is the LS9 head gasket is a compressed thickness of .051 which is the same as the 5.7. The LS9 head gasket would be the best choice of the ones you mentioned for forced induction.

Well I since the head is different I thought it wouldnt line up with the heads so I would be using a lq4 gasket but your saying the LS9 or the LS1 head gasket would work but the LS9 would be better ? Sorry about the stupid questions I just want to make sure I am doing everything right

Personally, I just want to make sure the bore of the gasket is larger than the cylinder so I agree with you, but I wouldn't say someone is wrong for running even larger than necessary, especially for a boosted application.

I know there is some debate on this. Some of the aftermarket heads have chambers opened up for large bores and so they'll recommend a 4.180" bore gasket for even a 3.898" bore cylinder.

Removed all my rubber hoses leading to my intake manifold with fuel lines
[/URL]
And Started to remove my ignition coils along with the harness

I tried to pull my manifold up and out but seems to be stuck in place I do feel some hoses and I unplugged the map sensor from the back but it seems something is still holding it in place any thoughts guys.??
