stock block b16 with sk2s2 cams..its a 1g block so i think they came from the factory rated at 10.2:1 ..i need to get the compression up to around 11:1 for these cams to work right....but i dont want to rebuild the block... i had the head resurfaced and they removed .005...i also have flat faced valves...now i was going to run an oem two layer hg but i dont think this will put me over 11:1..so i want to go with the middle layer of the oem hg....i believe this should get me at least 11:1...my only concrn is, i dont want to ruin this practically new head and maybe the whole motor, so i want to make sure the valves will clear before i do this...
now ive asked around, and it seems that not that many people are running these cams any more...im just hoping someone who has run a similar set-up can chime in...thanks

im already running a 3layer...i know a 2layer will work as well...but id like to really run a single so i can reach the minimum CR skunk recommends for these cams...my head has little to no milling at all so i dont think i will run into clearance issues...id just like to get sum feedback from people with similetups before i go about doing this...

will i run into any reliability issues running a single layer?

 

bump for more info

 

damn i guess nobody runs these cams no more

 

I believe the flat face valves will bump you up .4 then you should be right at 11:1.

see here to run your own calcs.

With out the valves you are at 10.6

 

really the flat faced valves yield a .4 bump in comp. ?...i always thought they didnt do much....i got valves,retainers,and springs as part of a kit from supertech when i got my valve job...ima go search around a bit, but if its true that the valves gimme .4 i can run a 2 layer and be worry free...thanks for the insight man

Sorry man I just checked with some others, and they think you can get a .3 bump. But if you mill your head about to 10 mils total then you will be at 11:1.

 

is it possible for a machine shop to mill a head without me having to take it all apart?

 

Yes, a shop can mill a head without taking it apart.

You will however have to take it off of the block.... I've heard of a one layer headgasket yielding a .2 bump in compression and as mar778c said a .3 bump for the flat faced valves. The bump from milling all depends on how much you take off of it. You may want to run the numbers as far as piston to valve clearance...maybe have someone clay your motor?

how can i run the numbers for piston to valve clearance?

what exactly is involved in claying a motor?
