No. The valves add roughly $200 in headwork. That offsets the extensive porting and the added material requirements and labor that needs to be added to the ovalports just to get them to seal.
You have the peace of mind that all stock parts will work with the hybrid and all you really need is the 3L exhaust valves, not the intakes if you are trying to save money. Keeping the 32mm intakes will improve the torque anyway since they are very similar to the 3L 35mm valves in size and in fact use the same external diameter valve seats. I would guess that I could convert an engine over to a 3L hybrid for about $150 in machine shop work which would include tanking and checking for leaks if I just improved the exhaust valves.
Then I'd probably end up with a fatter torque curve with the smaller intakes (also verified by Dyno2000) with some decent porting.
Every thing else would cost the same as far as gaskets.
If I did just the basic swap it is much less work than an ovalport hybrid along with a tube of jb weld. Everything just bolts back up and it ends up the same or cheaper cost with less work.
So it really remains to be seen which is actually better.
BTW, there has been NO ovalport 3L conversion to actually best the 3L hybrids in total horsepower to the ground yet.
If you count DavidZ and even my own motor, no one has actually beat them yet with an ovalport dyno. I was expecting the you might have a chance.....but to no avail since you won't dyno.
Who knows, maybe you're just a good driver with a tailwind and your engine really isn't putting out any serious horsepower.
Either way you'll get kudos from your engine build our your driving. You won't get both until you prove both.
