I have been reading all the info I can.

I'm wondering if regular LS1/LS6 heads will fit on this block?

Also, Have any shops got there hands on the LS7 and/or other parts for evalustion yet?

From what I have heard they will not fit.

i know that the LS1, 2 and 6 intake manifolds won't work on a LS7 intake. do the C5R heads work on a big enough LS1? if so then the LS7 heads should work being that they are very close to the C5R heads.

The only reason the intakes dont work is that the ports on the heads require the LS7 intake.

Those heads and intake are a mandatory pair for the use of either but the block I'd bet will work with all other LS series heads.

I understand how the intake and Heads mate together. The port arrangement is different.

I was asking if a set of LS1 or LS6 heads will botl right up to an LS7 block becuase of the changes made to the heads might move the bolts around to make space.

I would imagine they will fit. It thing the reason for a different intake is the difference in the head angle.

And the ports are larger. They require an Offset rocker to clear the extra space in the port so the pushrod doesn't protrude into the intake port. If that kind of work was done, the Head bolts may have been moved to make room. I've looked @ pics, but they only say so much.

I Don't care about the LS7 heads or LS7 Intake. I'm curious if anyone knows if the regular LS1/LS6 heads will bolt on. That's it.

The Ls stuff will all bolt up together. The only issue with ls7 is that the valve size of the ls7 head is too big to clear the bore of a 3.900 or a 4.00 block. But, everything bolts up from my understanding. So, LS6 heads can bolt on an ls7 block, etc....

Ah sorry, I guess I was thinking of the ls7 heads with the ls1/2/6 intake.

My bad

one quick question, why would you want to use LS1/6 heads? i hear that the LS7 heads are amazing!

but as normal i may be wrong!

Thinking that if/when the LS7 block comes out, youcan build a cheaper motor and still make damn good power using AFR 225 heads.

But, we'll all have to wait and see what the LS7 heads and intake go for. Might be better to go with that or (to save money) go with the regular LS1/2/6 parts.

im not an expert or anything but i thought on the ls2, the water jackets were moved to make room for the larger bore? or is the ls2 block the same thing as the 6.0 iron block for the trucks just cast in aluminum? just trying to get things straight before i start to build my V8 rx7

The water jacket's are siamesed. The coolant passages are not there in the LS2/LS7 blocks. That would not mean that they would have to move anything else around.

Keep in kind if you use the LS7 block you will have to use the dry sump system.
