I would like to get any review on theses headers and also the Summit Racing® Cast Exhaust Manifolds SUM-G9080. They look allot alike. I also would like to get some ideas on other shorty headers that would be recommend.

Save yourself the headache and get the Hooker cast manifolds. They fit well, and if you have them ceramic coated inside and out, they really cut down on the heat. That’s what I did.

Thats the ones I was looking at then saw the Summit and was wondering what was the difference. They look allot alike.

They very well could be the same product. We went with the white box oil pan from Holley...only difference was the name cast on the bottom...it was considerably cheaper.

white box? Thats my other part I was going with the H3.

Look on the Holley site. Their pans are well above the crossmember and require no notching. Worth every penny.

“White box” not a name branded on it.

This is for a 2002 blazer xtreme so I do have a little more room. I'm also buying mounts from Harley designed for the blazer. There does look to be a slight difference between the Hooker and the Summit. The Summit look more like the other cast header Hooker offers. Maybe someone on here has used the Summit ones. I really like the cast headers.

Summit also sells a set that in not specifically for an LS / S10 swap so be careful what you buy, make sure you get a set for the LS / S!0. I ordered a set from Holley at their Holleydays sale...they haven't shipped yet, they probably have a certain number cast at one time, good thing I wasn't in a hurry.

That is the major point. If the manifolds, or even headers, don't specifically say it's for an S10 LS swap, they won't work. The less expensive manifolds are for things like old C/K trucks or other wide vehicles. The S10 specific ones are tighter to the block to clear the narrow 2wd S10 frame. And naturally more expensive.

Summit has 8 pair of the Holley Blackheart S10 LS manifolds in stock and will ship today. Rather than waiting for them from Holley in CA. Whenever they get more from China. I'm sure all the container ships are full of face masks at the moment.

Agreed no argument here I was just curious if anyone had tried the blackheart and their thoughts on the money spent. Also wanted to know if anyone has tried to fit the Summit headers on their build. So they are more expensive because? There are limited applications is my thinking. Engineering is engineering.

 

[remops]

And BTW these are not for Blazers! Try to find a LS swap product from Holley that are designed for Blazers. You will find lots of products for S10 pickups but not Blazers. I have called and talked to Holley with that question. Have not received an answer. I even sent an email to the tech department have not heard back. So if I follow your logic if it is not designed for that application then it will not fit.

I think they are worth the money. Headers usually fit. Might have to ding them up here or there, or do some carving on the UCA. As long as you don't mind crawling under it every so often to tighten the collector's up...nah....I'd go with the cast manifolds. Loose 10 lbs and your can probably make up the diff from any hp losses... 🤣

I'm with you less chance of leaks, not as hot and should hopefully fit without a dent. I will be using a DD steering shaft. I got rid of the rag joint a few years ago but used the stock shaft now I need to replace the shaft.

I asked the same question a few months ago, s10dude said he bought the summit ones and they dump right onto the frame, they don’t fit. The hooker ones fit perfect according to him and rhot and a few others

That's what I thought I looked closer and you can see that they turn down where the Hooker stay up. Look at Rhotpursuit beautiful build that is what I'm talking about great work.
They are close to some of the others offered by Hooker. To bad there is not another option for a budget build.
Thanks

You'll have to clearance the dipstick bracket a bit. The hooker manifold flange is wider/taller than the factory manifolds and it didn't fit on @Rhotpursuit truck without trimming that up and using a allen head bolt.
