My 360 block has the stock spec.
So if I use my old 340 heads (casting no 3418915, 2,02 inlet valve) and a .039" gasket, no milling
should be necessary anywhere, right ?
And the quench will be around the ideal ,040 ,
( will of course have to check)

Is the.039 head gasket stardard in kits or do I have to specify.

So the 340 heads + KB 190 + XE284H is the way to go, I understand. Forgetting the alu heads also saves a lot of money.



The .039" is useally the norm in head gaskets, also, if i'm not mistaken (slep'd sence then), the 915s are J 360 heads, so your good to go, i would also CC the heads & make sure they are close to stock.
