Milling b16 head to rais comp.
Well we all know ways to incease comp withou pistons. However on my FI build i was just looking for advise.
Setup
AEBS sleeves
84mm
b20b block
cp 8.9:1 pistons
eagle rods
ACL race bearings
stock b16 head.
skunk 2 pro 1 or 2 cams.
Now I just did a full port job from www.Renown-Performance.com as well as had them install new Bronze valve guides and duel springs. also did a valve job on the stock valves.
I figured this would be a great opportunity to mill the head down maybe give the b16 a larger quench pad the the GSR heads. if i could get in to maybe 9.5 or heck even 9.8 id be happy.
How much can I take off the head? what are your thought on doing this.

I'm personally not a fan of skimming anything to raise the compression ratio. If i was in your shoes though and reaaaally wanted to bump up it up a bit i'd skim the block and head a tad and use a thin Toda head gasket.

Well at the cost of the toda I dunno plus i have the ls/vtec cometic gasket now.
if i could just get to 9.5 i would be happy.
Anyone have another thoughts?
I know its been done but i wanna see results or reasons.

That's the best way to do this if you're a bit stuck.

Re: Milling b16 head to rais comp.
Interesting, not to thread jack, but i was wondering this same thing about my vitara build, d16y8, p2po rods and vitaras makes 8.5:1 static c/r, would I benefit by milling enough to get to 9:1 ? And howuch would I have to mill to make this c/r 9:1 ?
