I purchased these from a fbud on this list here.
CC = 58cc
Intake Valve size = 2.05
Exhaust Valve size = 1.60
Intake flow @ .600 = 270cfm
Exhaust flow @.600 = 200cfm
Intake port runner size = 200cc

I arrived home from work to find this on the front porch...

Congrats on the new purchase!

 

those were 4s on this forum right? haha i woulda bought them but i need bigger combustion chambers good luck with em

 

Thanks Neil... I have to head to AZ this Friday, then Upstate New York next week. I'll be back in Houston in January If I don't have to go to Alaska for a new job. At some point, I'll get the new heads on.

 

Yes. Mickey had them for sale. They were/are in stellar shape. I ordered some new Canfield guideplates from Canfield last week for them. Mickey had been using Self Aligning Crane/GMHPP LT4 HOT kit rockers. My current setup has the 7/16" studs, guide plates and N/A CompCams 7/16" 1.6 promags. The Canfields have studs but they look to be the 3/8" versions. My turbo pistons were configured for 58cc heads so my 8.8:1 cr should still be intact. I have to use FelPro 1010 gaskets with the 4.166 bore for these heads. The guy at Canfield told me I have to make sure the water/oil passages in the 1010's are equivalent to the FelPro 1074's.
UPDATE! (10/29/2009)I do NOT recommend using the 1010's now that I've purchased them and tried to install them. I see NO reason you can't use the 1074's. Pictures occur elsewhere on this thread showing the crucial differences between the configuration of the water passage/oil drainbacks.

 

dave, i didnt realize you were running canfields on your car, i searched for couple hours on google trying to find info on them lol

 

I've had them for awhile but I'm just getting a chance to FINALLY put them on when I do the tranny swap (T56 out, TH350 in) this weekend (If the weather holds, no garage )
The tranny arrived today! Got all the major pieces. Just need a dipstick (Prolly a MadMan version), 12 qts of Tranny Fluid and a B&M tranny cooler.

There is like ZERO info on them. I even called Canfield themselves and they didn't know jack about them. I might as well have gone to Dairy Queen and asked the girl behind the counter about these heads. Sheesh....

What made you look for them?

 

guy offered me a set dirt cheap (600 with springs)
His have 61cc chambers though and 2.08/1.65 valves too

 

New FelPro gaskets and 7/16" ARP studs for the Canfields.


1010 gaskets up against the Canfield Head...

<Whistles> That's a REAL valve at 2.08".
Mine were a grand methinks. I had to have two seats and their guides replaced. They are all setup now, except for my swapping out the 3/8" studs and putting in the 7/16" replacements. You going for them? About the only things I came across was that George Baxter ran these heads with his S/C convertible LT1 Fbody and ran 9's.

Really crappy video's of George running the numbers. Damn near 8's in a convertible!

thats the ONLY info I came across too lol. I could not find a SINGLE dyno with them
I did find they were supposably "never sold to the public"

I am wondering what kind of port work were done to these ones since they have bigger valves and bigger chambers than all the other ones i've found.

 

Now that's interesting.... I did run across a few notes here and there that mentioned heads and intake fitment problems. I don't know if that could be decking and milling issues or not. I picked up a friends Intake and will bolt them up before I pull the heads to see if I see any differences.
Let's keep each other posted on this.

 

if i pick these up, you need new wheels though since we will be 2 of a dozen or so people with these heads, and we both have red lt1s. get GTO wheels and our cars will be twins lol

 

Dave, I want new pics of the car (with the new wheels) for my website.

 

Sure thing. Once I get her all back together, I'll get some pics.
Hope you're doing fine Jon.
