Saw this on Facebook Marketplace. The title had me thinking a steal on a set of Wenzlers, but the pic was a let down. I started clicking through them anyway and I started wondering what exactly are these?

Small Block Chevy heads, (AKA, corporate small block), after the real Pontiac engines were discontinued, Pontiac did some minor development work on SB and BB heads, actually made them better than Chevy managed to do in the prior 50 years and they were marketed for racing in the 1980's. Bolt to a SBC engine block.

AHHHH, couldn't figure out why SBC had Pontiac cast into them. I was aware of the BBC heads but didn't know about the SBC project.

[Brian Baker]

Brodix did these heads for Pontiac on contract with the SBC version typically steered towards NASCAR teams and the BBC heads steered towards NHRA Pro Stock teams. Pontiac designed them and Brodix cast them.

To expound on what Mike said, they were better than what the Chevy NASCAR teams had. Chevy teams began running them until NASCAR cracked down on them for not running Chevy equipment. Then the Chevy teams cried foul that the Pontiac teams had an unfair advantage and the heads were eventually banned.

I wonder if Richard Petty was running these heads when he got his 200th win (in a Pontiac)?

[Baron Von Zeppelin]

i think Rusty Wallace was running those when he won the Cup Championship

Petty rumor is they let him slip a Hemi into the car for that race

[Brian Baker]

The King won his 200th race in 1984 so I'm going to have to say no, he wasn't running these heads. I don't think these heads came on the scene until sometime in the 1988-1992 time frame.

If i even had a small chevy...

From what I'm reading. These sound like hard core racing parts . Not run of the mill type parts.

Great heads for a SBC. They were developed with help from Brodix and Pontiac for Nascar initially then for some drag racing. But the valve angle was different from a standard SBC and once the Chevy teams found out changed their heads. Those are some desirable pieces.

Just curious, would Pontiac valve covers work on them?

No. Need SBC covers.

[cdrookie]

So I guess the $500 asking price for heads and intake wasn't too bad(if they were in useable condition)? Almost wished I had a SBC.

[PMDJIM]

I'm thinking these wouldn't fit a standard issue small block. More like a racing block.

I recall they had a Pontiac valve cover for the head for the Pontiac teams.
