I understand there is going to be some variance between benches, Ryan, I was just trying to make a ballpark comparison. So, that being said, and with those numbers above, what would you say the best cast iron ported head below a W-2 would be for the money?

Cast Iron? Who wants cast iron? LOL Umm..............2.02" in a magnum, got to be best iron for the $ IMO. They have alot of advantages over old J heads etc. Better chamber, better wet flow, better exhaust (maybe LOL), lighter valves, round lock grooves, 10 valve cover bolts, just alot better catsings, hardened seats etc etc etc. Magnums are "the deal" IMO. Stuff an AMC pushrod oil lifter in it, hollow pushrods and run 'em.

He has just bought some w-2's for next years project. "As is", they didn't flow any better than the heads he's running now (same bench).
I could have told you that LOL. They will RESPOND to porting though LOL. 300/210 cfm easy

hey ryan, just curious if you'd cc'd a port yet, and how the port volume compares with some other "street" heads you've done

Any idea what the increase in flow would be using then MP porting templates?. I was also planning on going to the 2.02 intake.
Porting templates recommend 1.97 intake.
I ported my heads at home using the templates (with the 1.97 intake). With 6 miles on the odometer took a trip to the dyno, made 342hp at the wheels (with PS, Auto and an 8 3/4)

Look just like mine, real rough in the exhaust. With stock retainers/keepers I was way under the 1.64 spring height MP advertises, more like 1.595, but consistent. With hughes retainers (advertised plus 0.125, they were actually almost perfect at plus 0.045?) got me 1.64 for hughes springs spec'ed for 1.66.
I spent maybe 5 hours cleaning up and polishing the exhaust, definitely a lot a meat in the casting to machined area of the exhaust port, and around the valve guide.
The intake I only spent 3 hours (got the feel for the bit)as it was much "cleaner?" around the casting/machined area, but I did shave a good 0.080 off the pushrod pinch, and gasket match. Didn't spent much time at all around the valve guide, much more intimidating to me, hard to control the bit so I left it alone.
I also eliminated thread bulges where ever they could be found. This was my first porting (if you can call it porting).

wow 183cc, that's bigger than I expected...is that about the same as a ported 360 or eddie? the 302's, werent those down near 145 or was is 163cc finished?
one more dumb question: chamber size-- how does it compare to the eddies and 302's?

From what I can see, I'm in LOVE with those Magnum R/T's.......
If *you* love them. I wanna marry them.
Any more standard Magnum numbers?
LOL.....
Actually while the electricity was off here ALL FREAKING DAY....... I did manage to CC a Magnum Chamber. 63 CC's as cast.
As far as flow #'s.... no new ones to report, I'm trying to knock out these Large Port Commando's I have here before finishing the magnums. So it's going to be another week or so before I have new #'s to report, specifically exhaust #'s.
