Questions
Well I have some questions that i am sure i'm gonna get flamed for, but i did do a search. 
I found a alfa romeo 1991 164L for around $2,000. Its a straight 6, 3.0L, but 12v. How much of a differance is that 2 valves per cylinder make instead of 4 valves per a cylinder, performance and reliablity wise?
For a bit i want to keep it N/A so I would like to upgrade the piston's if possible. So my question is that, even though the piston isn't made for alfa romeo all i have to find out the size of the piston and i can buy the same size, but with higher compression ratios?
Also it has this ugly red pin stripe on the sides (its a black car) Is there an easy way to get rid of those?
Thanks for your help,
Tom

Re:Questions
well if the stripe is painted on, then no.
If you want to go FI eventually, then why buy higher compression pistons. It may be a low compression engine, but I am not sure.
You would have to get the measurements of the cylinders and rod lengths to make a set, not all that easy.

Re:Questions
on the valve question. heres an easy way to explain it. go to a coffee shop, pick up a coffee stir straw. blow in it. its a bitch and hard huh. now pick up a regular straw. blow through that. ok. so the coffee stir is your 2 valve motor, your regular straw is your 4 valve motor. 
ohh yeah, and you want lower compression in a turbo'd vehicle.

Re:Questions
Case in point, Civic CX is an 8 valve 4 cylinder. Produces roughly 70 hp. The DX has 16 valves, and a larger intake manifold, not really any other differences. It produces roughly 105 hp. Other makes (Alfa Romeo) are probably similar. If there was a 24v head available for that motor i'd start looking for it, if you're going to buy that car.
