What springs were you running on this motor?

was that an upsweep or downsweep test and at how many rpm's per minute. it looks like a nice combo.

I saw an unmodified set of the Engine Quest Magnums on a 2bbl circle track Modified tour engine Thursday. Pulled 444 tq at 5400 on a 2BBl 360. I didnt see the print out for the hp, but the heads were basically stock with a good valve job.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Jesse, that's a sweet combination. No reason for it to not have good longevity on top of the great numbers. And, with that torque........just think of them poor unsuspecting mustangs out there. You can take a bow for that one!

nice. are the RHS heads still available? how do they compare with the enginequest ones (which I see all over the place compared to the RHS's).
I am also curious how close in performance the EQs are, and if thy can be made to flow this these RHS castings.

I have had both on my bench at the same time. They are very similar but ave a few differances. The RHS has a slightly better intake port while the EQ has a slightly better exhaust. The rhs has more room to port but I doubt any one would use more than the EQ any how. The RHS head looks like it would flow a little better on the wet flow bench, the area behind the valve guide came up to a point instead of the flat area behind it like the factory head and the EQ. The pushrod pinch also had a slightly better radius to it. The Valve job looked better on the RHS, the seat came all the way to the edge of the valve 1.92 and the EQ could have had a 1.88 valve in it, that is easily fixed though. The EQ had a better exhaust port and real nice radiused seat. In a mild combo you wouldn't notice much differance in the two and a full boogy ported deal would be about the same, but someone trying to make max power with a unported head would be a little better off with the RHS but they are really more similar than they are different. The RHS is best Than the EQ than Stock but the EQ is definately closer to the RHS than the stock mag
