How about some flow numbers on all 3 heads? And don't show us some gay graph, we just want to see the numbers.

That's a great idea,especially since you are changing the whole combination. Hard to tell what changes are resulting in the increases

gay graph as requested
please keep in mind this was all done on the bench at Fonses - it seems to be a little stingy from the advertised numbers, but since they were all done on the same bench I can get a good idea on how things look side by side.
exhaust
intake

Is the super vic ported? That pup is makin some power with conservative flow #s and cam 
I gasket matched the intake, and also opened up the flange since it had that goofy overlap into it.
All the numbers were low - I'm not sure what caused that but they were all consistently low. The flow sheet from the MCH's add another 10-15 cfm in there and that is from his bench - I believe the test numbers were at 24" on the bench at the shop, but cant confirm that right now. but we did go into this knowing the numbers were low. I figure that since they are all from the same bench you can get a gauge as to how each stacks up against the other under the same conditions.
we had fun today finding hp - started out at 580@ 6500 - was way lean - needed to jet up ( was at 82 & 86 ) and timing was at 30 ( where the other 2 heads liked it AFR was in the high 13's and low 14's -  -
next pull had jetted up to 84 & 88 - made 609 @ 6500 - still was lean - about 13.8:1 - gettin there!
Last run of the day was 34 degrees timing and 88's and 90's - thats when we hit 12.5 afr and 627 @6500

108 LSA + 4

258/262 @ .050" Duration
181/185 @ .200" Duration
.426"/.430" Lobe lift
.639"/.645" Advertised Lift with 1.5:1 rockers
My cam is similar but with a couple differences..
mine is 105 lsa installed at 105(didnt want the added
torque with advancing it to increase the stall point)
the lift is the same but I have a few more degrees
on the exhaust side... same on the intake... with
basically the same compression.... I know your gonna
have more torque due to the stroke over my set up
similar to my cam too 254/262@050 .200 179 /184 cam lift 430/420 on 107 with 11.2 comp pulls like train with the indys , people over cam there engines some times these size cams are great street/strip cam
well done with the build with great info and graphs ,you will love going down the strip with that combo
