Anyone still using them???? What kind of flow numbers you getting out of them???? Are they comparable to a INDY -1 or EDDYS????

I have no flow # on mine. I have gone 9.76@135 with a 1.34 60 ft in my Dart. These heads are 2.14/1.81 that have been ported, had a lot of work in spring pockets and push rod area. Matt

All flow

I have a set on my shelf that went 4.86 @ 140, intake flow numbers were around 350, can't remember the exhaust. They have been ported twice, once by Muscle Motors when I bought them new and then a second time by a local Chevy guy who thought he could make them flow a little better, he's the one who gave me the flow numbers...that I have since lost. My combo was a low deck 500" striker, stock block, solid roller, injected meth in a 235" 4 link dragster. I have no complaints with them, won lots of money with them and never had one single issue. Yes, I've read all of the horror stories....

I know a little...These are the Chapman VI's (Zeus Castings) that go 381 peak but 335 @ only .500 and 361 @ .600.

That ought to work well with a long duration solid roller... LOL

I'm "Stage VI'd" out... let other people fill in the details on them.

whole thread dedicated to them in the archives.....

I have raised port stage VI but they are the standard port, not max wedge. If I remember right they max out at around 330 cfm. My car weighs just under 3800 lbs and runs 10.50's - 10.60's. Low rpm 500 c.i. stroker.

Thanks for the info guy's and ill try to find the post about them in the archives.

I have them on my car head work by compu-flow if I remember right Nick said they flowed 310 at .600 standard port head.I run a 451 and weigh 2950 car ran best of 10.09 131mph

No flow numbers as I ported them myself with templates early casting standard ports 9.40s at 142 2900lb ,solid cam 950 carb 496ci I think the key is not over cam or carb
