Yeah, they flow right with box stock Edelbrocks.. for the most part, only with a smaller valve.
Valve Coefficient numbers are real good too.
I don't have exhaust numbers with me, they're on computer at the shop... but seems to be in the 163- 166 range.

Int: 1.940 flow @ 28"
.050 39.9
.100 71.2
.150 104.7
.200 133.0
.250 160.3
.300 184.3
.350 206.0
.400 224.2
.450 238.4
.500 240.6
.550 242.6
 
Nobody wants Edelbrock performance in a 1979 PRODUCTION head, at half the price ?? Offers?

63GT,
Looks like good flow numbers. I don't see that casting # on my Mopar list. What are they off of? Are they for an LA small block? Are they compatible with a '65, 273 Dodge, 2 barrel engine with solid lifters, adjustable rockers, a CI, 4 barrel intake and CI exhaust manifolds? How much have they been ported or milled? Any pictures of that work? Who rebuilt them? What head gaskets would they use on my engine? Would cooling ports match?What is weight?
Thanks, Richard

They are late '70s production heads for 360 applications, and early HP 318 '81-'83.
I did all of the work.
I use the FelPro 1008 gaskets, if that's what you use, you're good to go. Just do some research to answer compatibility...
 
All 360 LA heads are open chamber. 66cc give or take... It's a production head, they vary
 
As long as your Magnum block is drilled for oiling to the heads... yes.
You can type in LA heads on Magnum blocks in the search box in the upper right hand corner of your FABO page for a wealth of info in that area.

You will also have to run the LA style rockers of coarse..
If you're using a hyd roller with the OEM Magnum roller lifters, will have to use custom pushrods to fit your LA rockers and short enough to run with the longer Mag lifters.
I have not actually done this before.. I'm just pointing out the obvious..
I'm sure someone here on FABO will be willing to steer you the right direction..

Thanks
