Default how much timing

ok well i got a p pump on now and ill be setting my timing tomorrow.

i got 5x.014 sdx injectors, 131dv's, phat shaft turbo.

i only want to time it once i dont want to mess with all the time. in the next 2 weeks its going to get 191 dv's, 4kgsk, 60 lb valve springs.

so i want to set the timing to what will work with those settings. i was thinking about 20*.

does that sound about right or do i need more or less?

20 sounds good as long as you get those studs in

so what is the difference in 16.5* as compared to 20* from the studs standpoint? will give more boost or what makes it worse without studs?

the big increase in cylinder pressure will stretch your stock bolts and cause your head gasket to go to crap.
