Use a lighter spring on one side to see if you can get the timing all in by about 3000 rpm.
Thank you Cobalt, i already put a lighter spring on one side and the curve is ok but i have definately good news...
Did you know that i'm an idiot? I checked today the lenght of the spark plugs hole in the cylinder heads (Edelbrock alu) and it's about double compared to the stock cast iron so the plugs i put on before were reaching just half of that!!!
poor engine...i just put the new NGK BRP6EFS plugs on and i will try them very soon, can't wait to...
