Manifolds or Headers?
 

Which should I go with. I got rid of(sold) the original manifolds on the 307 when I bought the blazer, but now I'm kind of regretting it. A buddy of mine gave me a set of black headers so that is the reason I parted with them, but they look kind of cheap and maybe not the thing to use. Should I just go to the junkyard and get a set of manifolds or go with the headers. Here's a pic of the motor I'm rebuilding for it.

I say manifolds On a stock looking engine.. headers if you are building it up.

Re: Manifolds or Headers?
 

:agree: If you go with headers, ask LUV what he put on GQ. They looked sharp.

Re: Manifolds or Headers?
 

2.5" vette manifolds.

Looks and flow in the same package.

Re: Manifolds or Headers?
 

What year Vette are those manifolds pictured from?

Re: Manifolds or Headers?
 

Around '67, I have a set also, bought from Pickemup, they are on a Corvette site but twice as much as I paid for them.

Re: Manifolds or Headers?
 

I put headers on everything.I had to buy el cheapos when in AZ when a manifold fatigued in`89.Cheap headers,no special coating/paint,and they lasted until I parted the truck in`04.I wanted manifolds since the truck was original and I had custom duals made right before I left.Couldn`t find any,so...cut and dogleg my nnew pipes.

Re: Manifolds or Headers?
 

I bought a set of new 2.5 corvette manifolds for $150 to replace my $360 ceramic coated Hedmans.

Re: Manifolds or Headers?
 

Manifolds..I have a grudge against headers..I bought a good set and still hate them...I love being able to easily access the spark plugs with the manifolds too.

Stock engine, I'd go with 2.5" Corvette ramhorns

Re: Manifolds or Headers?
 

Stock or not, i'd go headers if you've got nothing right now. If you had the manifolds i'd say use them but since you don't get some nice headers. I recommend Hedman, i've used them all and I thought their craftsmanship was the best. Also my headers were 130 I think and I think I got a hell of a deal, the other brands (dynomax, hooker) were like 100 bucks and for the extra couple bucks I spent on the Headmans, the quality is awesome. Mine are just the regular painted ones but the come in several finishes.

Re: Manifolds or Headers?
 

Ramhorns. Unless you have a serious build. They sound nice and are trouble-free.

Re: Manifolds or Headers?
 

These Corvette ramhorns have sparked my interest. What's the best place to find a set?

Re: Manifolds or Headers?
 

Franks Pickemup on the left coast was trying to have some more of them reproduced, but I don't know how far he got

Corvette America

These guys are around you and should save on shipping.

Just checked on the Summit site and Dorman makes the manifolds as well. There are two listings on the manifolds one for 60. and one for 110. Did not say they were 2 1/2", but you could check

Re: Manifolds or Headers?
 

http://www.performanceexhaustplus.com/ Best deal by at least $50. Both sides for $115. I bought a set. They are great quality. They don't even have the stupid air tube holes. Other places try to sell you these with holes in them and pass them off as '67 corvette ram horns.

Re: Manifolds or Headers?
 

i have a set of used coated headers id sell yah for 100 if you want them

Re: Manifolds or Headers?
 

what color are they coated, Keith?

Re: Manifolds or Headers?
 

they are that grey ceramic coating

Re: Manifolds or Headers?
 

Here's a shot of the headers that were given to me and a shot of my motor cause I'm proud of it :)

Re: Manifolds or Headers?
 

I ditched my Heddman's for the 2 1/2" 'vette Rams Horns 8 years ago. Good choice as they make as much power with my Crane 266 cam and seems like more low speed torque. They are quieter and you never have to tighten bolts or worry about gaskets. I think mine were both drivers side from a 63-65 and I used my bandsaw to remove the generator mounts. They were $68 back then, but you can still find them for under $80 if you shop around.

Re: Manifolds or Headers?
 

We could go round and round all day long.I`ve always put headers on my trucks and that was the first thing we all did with our trucks.Were we stupid or just not all technical back then?They sure seemed to run better.RV owners ran them for some reason,too.My engine builder throws manifolds away.I don`t hate them.But,I have had more trouble from them than headers over time...none with headers and three trucks with fatigued manifolds.Yeah,they were originals.But,that`s all I`d use.If I buy it`s headers.What ever you do in the future,you`re set.I change motors and leave the exhaust.Headers will never hurt performance,that`s for sure.When the factory builds a performance motor they design manifolds like headers.Look at Viper & Vette manifolds,etc.I like a tube per hole.Get that gas outta there.That`s what exhaust is all about.
I sell manifolds to lower the cost of my headers.Guys throw away stock intakes to buy ill fitting aftermarket manifolds for no to little benefit,yet argue over headers and ramshorns.Go figure.The same principles argued are true in both cases.That`s my take.

Re: Manifolds or Headers?
 

hmm so one thing that no one ask is what is he building his engine too or for..Ramhorns flow well. as well as any knock off block hugger. The manifold is designed for a purpose weather if be long short, equal, tuned. but if the guy is not building for power then what does it matter. What good is it to get the spent gasses out if you cant get it in. ie stock or rv cam, cheap intake, stock heads. Thats when these things come into play.

Re: Manifolds or Headers?
 

stock cam, and it's bored .030 over. Nothing real special

Re: Manifolds or Headers?
 

so the point there was... there is no real benefit 2 headers other than looks, and maybe a little hp, but negligible to the fact that there is not any more air goin in to get out.

Re: Manifolds or Headers?
 

Well since you already have headers, shoot some hight temp paint on them ( it will since come off but not as quick ) and hang them in there. You just saved some money.
