Okay I talked to Indy cylinder head today. The only heads that Arrowhead has at the moment that are factory rebuilds are a pair of 906 big block heads. They are out of cores.
They have sold out of the new heads also. As for the Lax and the max they are waiting for The Foundry to get them some more castings for building up.
The aluminum B Block. They have some on hand but they have 18 orders to fill right now. So they are building those Motors left and right as fast as they can. She said it would probably be a 3-month wait to get a block.
Now I asked her if I furnish my own course what would they build my heads for money-wise. She basically said that they would build my cores for what it would cost to buy their heads done. So $499 would get my 308 or 915s rebuilt with all new valves, new Springs, new guides, new seals, three angle valve job and then $100 more for 2.02.
Furnishing my own 915s that would actually be cheaper than buying the 915s from them.
