Sell the Stealths and step up to a max wedge port size or bigger My old pump gas Duster ran high 10.60s with ported big valve 906, ran 10.30 with CNC ported eddy RPM and ran 9.993 with a set of Indy SR M.W. size intake ports non CNC ported I did dyno test a set of CNC ported 440-1 on that motor and they where 50 HP better than the SR M.W. heads, I put the ported 440-1 on my bracket race 526 C.I. high deck 440 motor to sell it Bottom line is more air, more fuel, more power
Good info, Cab. The 906 to CNC eddys is probably the type of switch I'd be looking at. That picked up quite a bit. Just head swap and no other changes?
No other changes other than removing a set of CAT brand 1/6 ratio rockers to a set of Harland Sharp 1.6 ratio rockers due to the CAT eating up their shafts both sets of heads had 84.0 CC so the motor kept same the 9.25 to 1 compression ratio
