Head
If im looking to do a mini me swap and i get the Y8 head would i have to mess with the pistons at all? What would all need to be changed for internals and how much work is it? Im sure i could do all the work myself but im scared to mess with my pistons

Are you having any work done to the head, port n polish, valve/retainer upgrades, anything of that sort?

RE: Head
Changing the head doesn't require dissasembling the bottom end, and I don't suggest you do that unless you've done it before. And if you've never removed a head before, I suggest you do a LOT of research first, because there are a lot of little things you can screw up in the process.
And if you already have the head off, and you've got some cash. I would have the head rebuilt with a three angle valve grind, a mild port job, and put in your cam/springs/retainers of choice. If you were to take the whole engine apart, I would at least put new rings/bearing in, shot peen the rods, and possibly change pistons depending on your budget. That kind of build would get you some reliable HP.
If you plan on going forced induction, then you want to look at lowering your compression with a thicker headgasket and/or pistons. If you're looking at staying motor, then I would suggest having the head milled (you need to get it milled before you install it anyways) down a ways and get domed pistons.

damn i came into this thread hoping for a phone number.....oh well....[&o]
theres a lot of info out there about changing your bottom end and head. im pretty sure HMT (homemadeturbo.com) has a very good writeup on both.

RE: Head
a three angle grind is a job that you do with your valves. basically it makes it easier for air to move around your valves. i'll see if i can find a drawing of one.
porting and polishing is something you do to the ports of your head. theyre the holes that are opened and closed by the valves. porting makes them bigger, polishing smooths them out and reduces turbulence.
for valvetrain, look at Crower and Omni Power.
