Hi John. I am using 1.9 heads on a 2.1 engine because it raises the compression, thus giving more power. My mechanic has done this once before and the engine had 180 lbs of compression. The Bentley says you can go up to 189, so this should be OK, just use higher octane gas. I drove the van that had this done after 6000 trouble free miles, and it has noticeably more power. I am also getting a performance exhaust system from Fast German Auto, and will use Castrol 5/50 synthetic after the engine break-in. I have high hopes for good power from idle on up. I am staying away from big valve heads, hot cams, and all the other things that sacrifice low end power for higher rpms, and also sacrifice reliability. My engine should have a similar life span to a stock rebuild.
