From a 96 LT1.

The heads have been freshly built by Wayne Calvert in Denton. They are complete with fresh seats and valves, angle cut valve job, new LT4 springs and locks.

Unfortunately, I can't use them. They had been cut previously and he cut another .015 off to get them flat. That would put the compression ratio to 11.2 to 1 which is over the limit of the rule set I run under.

The combustion chambers are measured at 52cc.

These will bolt right on and you get a nice bump in compression.

Looking for $450 plus a set of good cores.

Heads are located in Ft. Worth, Tx.

Bump

Are they ported at all?

No ... unported.

Mitch, can't you run a thicker head gasket to get around the .015" he cut?

If the heads had only been cut once, yes. I would keep them.

But they had already been cut once before.
