Pontiac heads

Just looking at a 78 Trans am W72,WS6 option w/4 speed trans, They removed the B-W t-10 replaced it with a Doug Nash Race transmission, And to my question they upgraded the heads from the stock small valve heads with some casting #62 Big Valve so i am needing info on these are the good heads? He said it still has the original WC code Block in the car (WHAT IS A WC CODE BLOCK)just upgraded the heads has forged pistons don't know yet if it has been boared yet has true double roller timing chain and gears Harland Sharp roller rockers Hooker headers Flowmasters and 3.73 gears. Just need some opinions on this ride going to look at it today. and advice/ info would be great.

#62 heads- 72-75cc chambers, 2.11/1.77 valves. Used on 400/428 around '68-'69.

WC is correct block for a F-body w/the '78 W-72 6.6L option. This engine came w/the 'good' 6X-4 heads, 2.11/1.66 valves, ~93cc chambers, hardened seats.

Thank's Cobalt, I did some research but wasen't sure what the factory heads would have been. he has the paper work on the car says it is the W-72 WS6 option. I got to measure the sway bar see how big it is also. Thanks again Cobalt.

Those heads are actually very good d-port heads. The only issue you will see is the chamber size on the 400's, tend to see about 10.75 copression which will be rough on pump fuel. They were desireable back in the day for race engines and high performance street engines and work good. Did alot of engines with them. One of the things to do years ago with later year 400's with 6x or 4x heads was to just swap heads and alot of guys used these. They respond well to porting also. Hope this helps.

Did you pick up the car? Here's some info for picking pump gas friendly heads, that will give good performance. I like the 46s or 4C-5s for a street 400.

Here's a few pics of it after i cleaned it up detailed it , It was pretty dirty after the drive home and from sitting, It didn't have a pcv hooked up on it so i did that today i went to the driver side this time the passenger side valve cover was blocked off by a shied i guess, I'm just used to running them on the passenger side but guess it will be ok at-least it has one now.JMO

Well i tried to post some pics but i will have to re-size them but i did get them in my gallery if someone want's to check it out.

Cole, hope you don't mind, but I'm going to use some B/W for a couple shots- that's a SWEET ride!!

Are the door panels custom? I don't remember that style. A Doug Nash w/3.73's- whoot!

I don't mind at all Cobalt, You know i'm not sure about the door panels i will have to look into that, I know it has after market front seats and i really like them very comfortable they are scat seats. It pulls pretty hard with the Doug Nash and the 3.73 gears too i don't know how that trans is geared but i am going to try to find some numbers to find out.

Very nice ride man Always loved them ever since I saw them almost new when I was old enough to notice cars (5 years old in 1980). Of course, the Smokey movies helped lol How much did you pay if I may ask?
