Hey guys. Need input quick. Did anyone do a wiseco piston 10 1/4 upgrade and notice a heat difference coming from head???? It may be normal but after running for 5 minutes its so damn hot. Cant touch. Need to know if its bad or not before i do damage. Please help

i have a 12:1 its all in your head any air cooled engine will be too hot to touch it will be at operating temp upwards of 300* if not more!
