To be honest though I have to say that I can't see when they designed this head that they didn't take the swirl into consideration. They had to of.

I don't recall bashing you at all. As a matter of fact my last post said " I find it hard to believe that when this head was designed you didn't take Swirl into consideration" I said that cuz everyone is sayin that swirl is the problem in the other thread.

I started this thread by saying can my injector washer/ 20 over gasket be part of the problem?

I went with a 20 over gasket in hopes that I would be safer than a stock gasket since I didn't want fly cut pistons. With the 188/220 cam that is.

Well I didn't think i would have had a problem I thought it would work just fine or I would have called lol. When I posted this earlier I didn't think to call you because I didn't think your cam or head where the problem. I just figured I throw it on here to see if anyone had anything useful to say. If anyone else ever had this problem and it could be an easy fix. But back to the 20 over gasket and way it was before and after. The block was decked which also took away some so the 20 over really wouldn't be 20 over what it was before cuz the block is now slightly lower. Correct?

I knew this would bite me in rear lol. What that really means is I don't have time to type a lot right now and seems that putting this head on has some how cause a problem that if I just reused the old head I probably wouldn't have right now. But $3600 is a lot for a head. However I am still hopeful it is worth it.

well how much is the block decked? if you went with a 20 over gasket and you only decked the block 5 or 10 the you have moved the injectors 10-15 thousandths away from the piston which would cause smoke issues. and you have also changed the compression ratio of the cylinders.

See this is what I was looking to hear earlier. really I was looking to hear put thinner washer in and good to go, just cuz thats a lot less work, but either way.

well a thinner washer will drop the injectors but that depends on the decking of the block, the head gasket thickness, pistons. the other issue is the fact about the reduction in the cylinder compression ratio.

I suggest you stick to Legos, they're made to just be thrown together....

My truck is set up very similarly but I used a stock thickness gasket and the thinnest washers on my injectors. I also have quite a bit more fuel and turbo. The truck is slightly more smokey than it was before but I went to 5x20's and a maxed pump. This is with a gt4202 single (75/82 1.01). I can drive in traffic fine with out smoking to bad givin the setup but it did haze black before I played with the afc some. I have seen .20 over gaskets cause more harm than good but almost used one for clearance as well. I noticed the biggest change in smoke was related to dv's pump had full cuts which are nasty, swaped in some 191's which were not much better, then some 181's which work pretty good, didn't have any 131's to try or I would have. I hope this rambling is making sense.

Im still confused as to all this. It makes sence with the thicker gasket, more space, less compression, ect, But Adam had 60 taken off his head then used the 20 gasket, and a stock gasket I believe. With the same results. If anything even if his pistons were shorter than the stock ones he was still closer than the stock setup seeing as he had 60 off head. Correct?

Material taken off the head will not affect compression only valve depth

ok, yea, Not sure what I was thinking. Just trying to figure it all out at once I guess.
Thanks for the info though cliff. On your setup you said you went to 5x20 at the same time you put the head on right? What size where you running before that you are using to compair how it has more smoke now than before?

Decking the block will have an effect on compression tho

Is this part of the reason you made some ungodly high compression pistons to make the head street friendly?...
