Exhaust timing

[Jug]

So I measured my exhaust duration timing and it came out to 165 degrees. Which is pretty s**tty. I raised the exhaust port getting it to around 170. Im doing all this to get a better powerband, I also made my exhaust port more circular. So should I try to get my exhaust port timing to 180?

Also, I haven't done s**t to my transfers yet, except matching what should I do?

Re direct the transfer ports towards the intake to get rid of the cross talk.
Makes a world of difference.

Setting a proper squish gap and a properly tuned expansion pipe will have a way bigger effect on power than adjusting your port timing.

Be careful not to go too far on the exhaust port or you will lose low end torque. Another way to adjust the timing by using a 2nd base gasket and modifying the piston skirt to readjust the intake timing. Check out this video.
