Default Warhawk LS7X 12deg.

The very first 12 deg, 255cc head in for testing and approval. If all well, ship mid-late Nov. Will post flow toward end of this month.

I know you answered this question before but I can't get the search to work.What springs will the assembled versions ship with? Are the intake ports different dimensions than a Gm LS7 head? By the way they look too sweet for words, can't wait to see some results.

Are those casting holes in the intake port?

The exhaust side. I see the extra head bolts holes but I am guessing this will fit the Warhawk block especially?

Looks like a LS7 intake will work on these.

Guys,
To answer the more basic questions, go to www.worldcastings.com. Then click Cylinder Heads, LS7X, and our sister site (for pricing) www.theengineshop.com (they're linked on the homepage). Most of the stuff there is correct and the minor revisions I'll outline on Mon.
See you on Monday.

The thing I wonder is why the ear cast out on the bottom head bolt? Seems like it would be more prone to breaking off over having brought out the lower edge of the casting?

BTW , I have a customer waiting, well be in for a block and heads . He is a serious abuse tester so build them strong please.

Good Lord... gonna need some 2" primary headers to "optimize" those massive exhaust ports... and ultimately the sick bump sticks.

It's good to see this moving along. Can't wait to see the whole package completed and running.

I was kinda wondering if there will be a 481 shortblock for the 12* valve angle. Or is this not possible with this geometry and the long stroke? (Sorry if this is old info, I only occasionally leak over to the LSx sections.)

The tall deck block which was designed along side this head was made to acheive 481ci.

The block is availible in both 4.000" and 4.125" bores
