I think I heard that phrase before, we'll pass it to see what's in it.

So !! a set of closed chamber iron heads is more expensive than a new set of aluminum heads ?? Whats next ?? the cam is hard to grind with the stock lift ??

This replacement head deal is way out of hand, there are plenty of good stock casting for SBC and oval port and square port BBC, you just have to get your wallet out and there really not that expensive when your building a competitive stock or super stock Engine, And no you can't buy them from jegs or summit.

If anyone needs some 906 cores I have 40 to 50 heads.

That's hilarious. How many heads and engines do you build? And just how good are you at welding cast iron heads for Super Stock?

I was talking about stock, super stock is a whole different deal, if you're welding heads for stock eliminator then something isn't right.

Really? Read your post again. I quoted it for you. You said stock and super stock.

And a set of used up, worn out, possibly cracked castings can cost you over $2,000. I know one guy who has been trying to find one matching head to replace a legal head that cracked for some time now.

Yep

Hi All,

The reason that most of the replacement heads are only legal in Super Stock is that they have to be modified by filling in the runners to the correct cc's.

You can't weld or use epoxy in the runners of a Stock head.

Combustion chamber volume can also be adjusted in SS and not Stock.

The replacement head just supplies a blank sheet of paper to start with and can be made legal by machining.

Whatever you use it must conform to the NHRA Blueprint Specs including valve size.
