LS7 head bolts/gaskets etc In the GMPP the cylinder heads need specific gaskets [how come std ones dont fit?]
and the corresponding parts also talk about bolts the question is do i need these bolts on a crate engines as im guesing the bolts are used to refreshen used engines or are the bolts head specific?

Well Pete, you lost me. What are you looking for? You talk about crate engines and then cylinder heads, gaskets, head bolts. Crate engines are fully assembled.
INSTALLATION NOTES
• Assembly does not include any electronics.
• Comes assembled with 14" Corvette Z06 168 tooth flywheel.
• Comes with 58X reluctor wheel and camshaft sensing and is not
compatible with pre–’06 ECUs.
• LS7 is the same size and mounts the same as previous LS series engines.
• ECU and wiring harness kit, P/N 19166567, available for non-Corvette
applications. Kit includes electronic throttle pedal, which is required
for throttle input to the ECU (see page 357).
• Use oil hose adapters P/N 25534412 to adapt to -12 AN fittings.
• Intended for pre–1979 street vehicles or any off-road vehicle.

We have been through this before. The GM LS7 head gasket is a 4.150" bore. It is made a little diffent than the LS1 style gaskets, because the water jacket holes in the LS7 block are just a little different. I have had several discussions with Cometic on this issue. Any of the LSX head gaskets will work though as long as the bore is big enough!

Cheers for the answers but in the GMPP mag page 279 [corresponding parts]
it lists the gaskets and bolts are the bolts head specific or are they listed just to refresh the bolts you take out when you remove you exsisting heads?
Sorry about the numpty questions just need to be clear.
