well, i do know that these heads had the large 194 valve for the 305 heads at least. i know compression makes power, but flow is a must.. but Im 19 years old and im sure you know plenty more than i do. Unfortunatly im just trying to get by with what i have right now.. and i am capable of doing some porting on the heads myself. unless its just a pure waste of time. being 53cc with the pistons i have this would be almost 11.1 compression maybe to high but this isnt my daily driver.

as for the cam, i shouldnt have said it as i did i apologize.. it was brand new when i put it in my engine, it just wasnt in the box and it was lost.

i did have this engine assembled with these heads and cam. New oil pump and all. unfortunatly i was forced to start the engine before i wanted due to my graduation project timeline.. not as clean and such inside as i wanted "bottom of oil pan". I figured out today i spun the #8 bearing and im thinking being its closest to the oil pump it got all the gunk first causing this..
