Yeah they've been beat up a fair amt (on here) but we are (pretty much) about posting probs to be solved rather than noting how many houses Jimmy Carter built in a given year. The salesman was nervous when he picked up the ph as I did punch in 1167 1st but when I started conversing he calmed down when realized I was not a telemarketer nor was intending to get in his a$$. As a person who spends more time than I am comfortable admitting to in Harbor Freight I have no significant prob w China stuff and tho I am as patriotic as the next guy (I think), but so much stuff is being outsourced these days that I'm (pretty much ) used to it & am (much) more concerned with getting quality & that is declining everywhere.

The thing with a new head that has to be ported I would like to see or hear of someone that has done a set to see where the problem points are(thin areas to the water).... or is it worth it to get them CNCd... I dont like going into a port job without any knowledge of the port... and most likely your valve wont be the proper length required(just guessing) also who makes rockers for the head and price.... I just dont know anything about those heads

alright from scratch what I have is a set of NIB Manley 3/8 2.14/1.81 valves, a pair of bare 915's. a pair of bare blasted 452's a pair of cruddy 452 take offs complete. A 451 coming together and a 535 RB next (have block/4.5" crank). Top priority right now is heads. The KB pistons have the tall machinable dome & no idea where my height is going to fall but want to run pump gas & definitely want .040" quench. Double R I had just assumed that if the dia is not an issue and can ream the guides then I assumed the height would be the same/close. The "supers" have seats/guides installed & I'd have a guy ream the guides and I'd port them myself. That's the plan stan (so far). I'd think the larger supers would be the way to go unless you guys persuade me otherwise
Do the stealths use the same length valves as a stock iron head?
do you have a flow bench ? Have you ported Ebrock RPM's in the past with good results ?

why not just use a set of 88cc edelbrocks? pistons will fit with little to no machining. sell the manely valves, and happy motoring. 
88cc Ebrocks are OPEN CHAMBER heads ... BAD choice unless he already had a shortblock built with KB step head pistons sticking .060-.100 above the deck.

Dammitt Kilroy  I just may have to as Capitol 1 wants to send me some plastic but the quality control issues are worrysome but 471 said they have a warranty avail which might be good preventative medicine
Ya , make sure you get them all done and figure out in something like 45 days ...  ...
471 said he had to pony up another 400 out of pocket to replace his defective head if I read in incoherent post correctly...

My vote is for Victors personally. The super stealth heads are intriguing, but I don't like the super thin spot next to the pushrod hole. The less thin spot by the bolt hole doesn't bother me as it can be sleeved (as can the oil passage to the rocker shaft) but it's time consuming and a pain without the proper equipment. You already need to get .650 offset rockers so there's another reason to go Victors. I don't think the standard stealths should even be a consideration on an engine that large. I'd rather see you run cast iron stuff to save your pennies so you could afford good heads later, but that's just my  According to their website the super's use stock length valves and based on what I've seen with mega ported perf RPM heads, 345 cfm isn't impossible by any means, so I assume these would also be capable of that or more due to the wider pushrod restriction. As I said, intriguing, but I'd rather see a bunch of others experiment with them before I throw down the cash for a set. Just for comparison sake, I did a decent valve job, bowl blend and gasket match on a set of max wedge victors that flowed 355 cfm at a reasonable .650 lift and that could be achieved in three or four hours. On the RPM's that flowed 345, I spent three or four hours on one port and it hit that number at about .725" lift and went turbulent. Also had a 2.250 valve. Dollar per headache, the victors are the winners. Look stock while still performing fairly well (but not as good as the victors), the super stealths win in that department.

This 535 RB is going to be a daily driver pump gas (87 octane) 65 dart. Extremely conservative cam. That's the plan so far unless my mind changes

john, the OP said he had kb pistons. the only kb 451 pistons i know of have quench domes. the 88cc edelbrock is a perfect fit for kb quench domes, .

You may have missed his other sillyness regarding the use of that piston , cut the dome for zero deck with a closed chanber head.
I don't know how hi that quench dome is on that piston , he may have too much piston to head which can be worked around by cutting the heads which may bump compression too high ???

my thoughts were; if you have a quench dome piston use a non-quench head. the dome can be milled for closed chamber heads; just a hoop i wouldn't jump thru. to me this is a simple project made difficult.

I am glad that when people say "Buy American...Support the US worker" people go and buy the Chinese stuff...Yeah I am guilty too...I buy Chinese stuff but I also don't live in North America...but when it comes to my car...I don't skimp out on parts. I bought my 4.15 Crank from 440 Source when he was just one guy, working out of a garage in San Fernando Valley with 4 shelf units full of BB heads. I spent the extra cash on the "other" heads...
