Revving high in upper gears

[rockinthe40ounc]

When I shift into my upper gears (3 and up) my engine starts revving incredibly high, even when im not on the throttle. The only thing i could think of is that my head gasket is blown (you can see it blowing exhaust on a small section). Any ideas?

and jetting but if its blowing out exhust its your gasket like u said it wont have enough compression and thus not getting the exhoust away makes it too hot to run so u can not start it till its cool do a compression test

DO NOT RIDE IT UNTIL THAT GASKETS CHANGED...........with a airleak like that you are lucky it didnt melt the piston....thats ur whole high reving problem right there
