From what I've seen, I'd still say no. Junk castings, assembled with even worse junk parts. And the ones that I've seen flowed were way down from advertised numbers.

The Edelbrock E Street heads are just over $900 a set. They have also upgraded the valvetrain to remedy the issues that early versions had.

I feel the same way but just in case I fell behind in the "what's new"  dept I wanted to get more information.

As I near completion on my 347, I parted out my old 302 and sold what I could on Craigslist.  I optimistically posted a set of Pro Comp SBF heads at $200 and you would not believe the stampede of people trying to buy them.  Obviously I underpriced them...  I just dont understand why you would sink 6-800 bucks into those cores with the available options.

Any feed back on these? Note in the text they are not Pro-Comp I guess they parted ways with them. http://www.skipwhiteperformance.com/detail.aspx?Item=NKB_SBF274

I'd pass.

I'd buy some used name brand heads before I gambled on those.  An extra $3-400 will get you a lot more.

  Did you read the ebay link ? They are assembled using Comp Cam components so would that not be a quality improvement over unknown parts ?

They are still low quality castings. They are known to have guide and seat issues.

And just FYI, Comp does sell some lower quality components. While probably still better than Chinese junk, don't be fooled into thinking that they use the same quality of components as a TFS or AFR heads. Probably not even remotely close.

Can't comment on their cylinder heads, but the distributor that I bought from them a while back, which was basically a GM HEI applicated for a SBF, was total garbage in therms of build quality, machine work, quality of parts used etc.

as far as skip white and the 700/set  thaats for a basic set. you want anything more such as better valves, seats, etc   youll be over a grand in to them.  I looked into them when they had the 3038 at same price. you can get the pbm / erson  components, they will put in better seats. not worth the cost. on the other hand a engine builder sold me a set with good components at his cost just to get them out of his shop.. been on a stock 351 block with a small hyd roller cam.  been in a ranchero using as truck and club racing, about 8 times per year. no valve train issues thus far. have put about 8k since installing.  they work for a set of 400 dollar heads. and about the same flow as mild port stock smog heads  130hp engine now making about 280 at wheels, not much of a motor
if ya really want power gotta get the ones that actually flow,
