Well if he's your head porter guy, believe him. He must be pretty smart. I've CNC ported 53 sets of them and I didn't know that.

P.S. If he finds any more of those early C-460 heads that are not worth using,,, I'll take them for the price of scrap aluminum and pay shipping on them, if he'll send them my way. Wink

Gerry,he might be mistaking the C head w/one of the other older heads. Charlie knows them all as good as anyone. If I have any head ?'s ,I always call him.

There was something going on.
The 1st C460 engine I did had WW rockers....the intake rocker tip was very much off front to rear. I expressed my consern......WW person said I had the right stuff.
Two years later I needed some replacement parts....the person that answered the phone said.....your the guy that has the wrong stuff....WW sent me the correct stuff that hit the valve correctly Cool .
The new stuff landed on the tip of the valve ~ correctly.

Bottom line is...there is some early stuff that has the intake valve closer to the cyl. wall.

No, I really haven't. Very Happy I just got really tired of doing cast iron Buick Stg 1 heads and always getting my eyeballs drilled to get the metal out. I don't have nearly that amount of trouble with aluminum heads. It's due to the smaller size of the chips between cast iron and aluminum.

The BB Fords make so much more power and Lem is the one who really introduced me to them. I've only been doing them since the late 1990's. Very Happy

From time to time we do have core shift problems with the C-460 heads, (afterall they are castings) however, I can't blame that on either early heads or late heads. They did more a valve guide centerline over several thou., it was the exhaust I believe, and that was very early stuff. That doesn't make the heads "not worth using" though.

Yes it was moved over .030" towards the intake becuase of guide failure causing the valve to hit the cylinder wall on smaller bores or so the story goes. I wonder if he actually has a set of D heads with the Pro stock block bolt pattern? Since the only difference on an early C/D head is the head bolt pattern it is drilled for he may be thinking it is a goofed up C head Suspect Laughing

C-460

Post  Gary Blair on Wed 7 Nov - 11:09

The first C & D-460's had the exhaust + .030 away from the intake valve. They also had a problem with exhaust guide failure because the guide had a taper and would crack. If you have these just install a PPC blunt nose nickle bronze guide. You can also get a larger intake valve in these early heads.

Wilfred has stands for the early and late exhaust valve placement.
