ok so i got my head port and polished by alaniz and they went ahead and milled the head as well. i should be getting it back any day now so i'm not sure exactly how much they milled it yet. my guess would be .025-.030. anyway my question is. if i install everything and the cam gears are at 0,0 and the ignition timing isn't touched. i know its not going to be at stock because of the head being milled however do you think it would be at a safe degree of timing to run till i break in everything and go get it dynoed. aka 1 week tops?

 

anyone?

 

Getting the ignition timing correct is no problem. Just time it in the standard way. The valve timing is another matter. After a head has been milled this much, valve timing is going to be retarded by a degree or two. You are NOT going to be able to line up all the timing marks. Your only recourse is to get a pair of adjustable cam sprockets. Once you have the sprockets, you can adjust the valve timing by using the holes in the cams instead of the timing marks on the cam gears. If the motor is a DOHC VTEC, these holes must be lined up with holes on the cam spraybars. If the motor is a non-VTEC B-series motor (LS or CR-V), the holes in the cam must be lined up with the cam bearing caps which also have a hole on top. This must be done with both the intake and exhaust cam. And when the holes are lined up, the crank needs to be at TDC (while mark on crank pulley lined up). After doing this, reset your ignition timing.

I am not sure how this is done on a D-series motor, though.

 

oh sorry ya should have listed my set up.

b16a2

j's racing cf intake
jdm dc 4-1
carsound 2.5 inch high flow cat
greddy evo exhaust
hondata IM gasket
spoon head gasket
skunk2 intake manifold
skunk2 stage 1 cams
skunk2 cam gears
ITR valve springs/retainers
b&m FPR
vafc
chipped p28/ by kenji
exedy organic clutch/ exedy 9.8 pound chromoly flywheel
competition port/polish/ 3 angle valve job by alaniz, and head milled for around 11:4 compression.

thats my set up. i didn't know that i would never be able to line up the timing marks on the gears now. hm

update. head was milled only .015 when i got it back not the .025 i thought it was. is the timing going to be sufficiently off cuz i wanted to take it to honda and have the timing belt replaced and i don't want them to be ultra confused when the timing doesn't line up.
