Olds 303 head question

So I was wondering if anyone has any idea why my valve springs are bigger on one head? I have looked in my shop manual and it dose not say anything about it in there. I have never seen anything like it myself. The spring perches on both heads are the right size in relation to the spring, almost like one of the heads is from a different engine?? Strange

 

What are the numbers on the heads? Might have a later 324 head.

 

49-50 used a small spring, 51 on up Then they went to the 1.500 springs

someone changed a head at one point

By posting this, you are now a Rocketeer. Do a search for posts by the late, great Don_Wow on the HAMB. You will learn a lot and it's good to keep those archives active. Good luck.

 

Thanks for the tip on Don_Wow Chili Phil. Every one I talk to around my area keeps telling me to ditch the rocket and go with a 350. Just makes me want to keep the 303 even more!

 

I second what Tony said.

Get yourself a set of #10 heads with a 4bbl manifold and show those 350 fans nothing but tail lights.

 

Yeah Id take the easy way out and dump a 350/350 combo in it

Who'd want anything like these under the hood?

Of Course Im partial to the Olds!!

Chili -My car must be a Super because it already has a factory 4bbl intake and carb..?. Its says Olds 88 4s on my ***le. I think its cool they did that to a more door back then.

Damn Goat, you got me all worked up over those pics!!!

 

Yeah, knock it off, Tony. The plastic cards keep jumping outa my wallet!!
