I have purchased a few pairs for big blocks and liked them. I only tried them because of my main supplier (EPW) had them and has virtually no complaints or comebacks. Performance level was good. I guess I will wait a while longer and see if there is a reliability issue. Gut feeling tells me, so far so good.
A had a few people ask about these heads but now for many people it is all about the AFR or for people who want alu. and are on a budget and want made in America the new Brodix IK seems to sell well.Quote:

I have not heard anything negative about them on other websites. They say they are good quality heads that are made down under.
Aussie heads....hhmmm.....I'm anxious to see the end results for longevity and reliability.
I have the Pro Topline heads on my 418W and they are great after 12K miles!!
No issues whatsoever!!
Sorry to resurrect a ghost thread.... but I had to say something....
I just bought a pair of these for s SBC, got them assembled and on the engine. They are machined to accept both perimeter bolt valve covers and centerbolt. Aluminum perimeter covers rub the stamped steel rocker arms on the pushrod end ( I ordered 3 different sets of different brand covers, all resulted the same ). I have ordered a pair of Edelbrock Aluminum centerbolts this time and I am going to try them. They should arrive tomorrow. I will repost the results.
I will add that I am a bit disappointed in the casting and finish machining of these heads. Although you save a couple bucks, do yourself a favor and spend the tad extra for a more reputable head. I have a feeling that in the end, I will wind up having to buy 2 more heads.
This is with the stock height covers, right??? Just looked over a pair of the Topline heads that a friend bought... They have had lots of port and flow bench time on them...didn't hear the flow numbers... Anyway, the runners and chambers NOW look great, but the outside is still a bit less then show car stuff... These heads are for a competitor's car, so I'll let ya know how the performance is in a month or so when drag racing starts...
First pair was stock height, second pair was the Edelbrock Elite Tall ( and, boy were they tall...). I should have been a bit more specific... the rocker is rubbing the valve covers on the side that is facing the carb ( sidewall ).
I've had the same issue, but never with stock rockers... Must of really had things off when they drilled the valve cover holes...are the holes even centered on the rails????
Don't know how much they're hittitng, but the Edelbrock covers are quite thick, maybe a bit of die grinder time on the inside of the covers would at least make the heads usable??? The covers on the dude's heads I mentioned fit fine, but he's running a set of Comp arms on it....
OK, got it settled. Had to use centerbolt covers and it took care of it.
Glad you got it fixed Weasel, guess the centerbolts must be a bit wider on the inside or something.Quote:

After studying the rocker arm - valve stem contact point, something don't look right. Summit says the screw in studs I have are for use with or without plates. I got to think on this a bit. Have you ever had the feeling of just not trusting something... no confidence in it ? I am about ready to invest in some different heads.
I'll try to post some close up pics of the rockers.
How is this old thread up again?
I figure thats what the chevy guys do for attention with the small valve heads they think are big. My stock Ford small block 351 Cleveland head came with a 2.19 intake valve and a 1.71 exhausts they also came with guide plates from the factory.
HE! HE! HE! Well Dave you think this will get any of those little head chevy lovers going.

hope not me :3dSMILE:my heads just have a 2.400 valve:)Quote:

On the 392's we couldn't get past 2.100x 2.000 or they would hook together on overlap--with the Donovan alum heads changed the angles and eliminated some of that
just cut some ti valves 2.350 down to 2.325 and 1.900 they get close with a bbc 360 dart START RUNNING OUT OF VALVE SEAT :) CANT HANG THE INTAKE 45 ON THE EX SEAT:HMMM:I JUST CUT down SOME BBC INCONEL VALVES FOR THE 37 CADDY works good i hold the valve in a 5C collets
Ya But arn't those BBC Valves!!!
Mine is a small block Ford.
Also did they come from the factory with those big valves?
My small block did.
Kurt
big valve s are not every thing . them 351 c heads get the A &B putty JoB ports are to big . yes my heads came with 2.400/1.900 .most bbs are 2.065/1.725 not hard to stuff a 2.250 /1880 or 2.300 if you feel the needQuote:

The only thing the big cleveland heads are good for is all out racing.
For the street the 2.05 are much better, I know they started building the
cleveland engine when the emmission crunch came in to play.
Then they did away with leaded fuel and dropped the octane in the fuels.
Back when it was built though I was still able to buy about 112 octane and higher
from union 76. At least thats what I was running in my old BB charger with 11.5 to 1.
Today unless your racing it all the time, the big valve cleveland heads are not very pratical.
Kurt
But my point is them big valves still came in a small block Ford.
HE! HE! HE! Not a big block, but a small block.
Chevy lover.HE! HE! HE!
Just kidding Pat.
WELL...... it s funny that the 351 head looks alot like a BBC head used the same rocker arm as a bbc if you go roller rocker:3dSMILE: the hp bbc came with 2.190/1880Quote:

There is only one American made engine that ever won a "World Championship" only one. Care to take a guess ????
The Ford 289. Its the one and only when it comes to that...

Thats news to me, I'll have to stick that under my hat for a rainy day.
