A few engine building questions

[pachood]

So my block has a bit of rust pitting in the cylinder walls. I recently had my block cleaned, checked, and honed, but the pitting is to extreme to let it slide. I have all new parts for my motor, from a new oil pan up to a freshly redone head, but iam stuck on these cylinder walls. I was planning on boring it over a little ways, but my machinest is a small block Chevy guy, and I was told to only bring the motor to a 4g63 specialist. So what to do now? Should i go with a bore? Should i just try to find another block? If i do get my block bored, should I be purchasing a cometic msl oversized gasket or just use my Fel-pro standard gasket?
Any help is highly appreciated.
Oh, and by the way
i Have about 1000 dollars sitting in my bank account to spend currently.

Depending on how bad the pitting is I would have the machinist bore the block over .02 to .04, it all depends on how bad the pitting is. also, I would have the block magnafluxed if it has not been done to see if there are any cracks in it.

The block was cleaned and checked over. I was just told something about not being able to bore these walls without the machinest knowing 4g63's because of their "floating cylinder walls". Now i have Never heard of a floating cylinder wall, so i guess i have no idea what he was talking about.
So would i be able to use my felpro standard gasket if i did have this block bored?

If i was you i would save some cash and buy a 2.3 stroker, might as well when you got it ripped down or at least put some forged internals. A mls 4 layer head gasket will do fine. i had all my machine work done at a local shop that does more V8s then anything. my motor was referred to the little mitsubishi motor.

4g63's arent floating cylinder walls thats honda crap. as long as they are a good machine shop it shouldnt matter whether they do mostly v8's or not.

Im not certain where i would be saving the money there? WTF But i thought about just stroking it, but when im playing with a grand i dont think i have that as a choice. Also, the new head bolts i already have are not ARP so i also need to go pick up a pair of those.(100, and the mls head gasket, another 100..oh, and i forgot to pick up a mitsu oil pump) Do they make overbore sized pistons for a stroker?

Thanks for the help so far!

Find another machinist. This guy apparently doesn't know much about anything. The 4g63 is a closed deck design and can be bored the same as any small block. Did he even really look at the block? I find it hard to believe that a machinist can't tell the difference between an open and closed deck. Hondas have the infamous "floating" cylinder walls. What this means is that the area around the cylinders is open. Like this:

You can see the area I'm talking about pretty clear in the pic

The 4g63 doesn't have this open space around the cylinders. If you find another shop just have them inspect the cylinde bore and let them determain how much it will need bored out. If you already have new pistons you should return them and wait until you find out about the condition of your block. Use the Mitsu MLS gasket or the Cometic one. The Felpro won't hold up for very long depending on what boost you run( mine lasted 1 1/2 years). Save yourself the frustration of doing everything over again and just do it ritgh the first time.

Ohh no, sorry i didnt make myself clear. it was through another person who i was going to buy a set of wiseco pistons from, Not my machinest, BUT thank you for making that clear to me, i have never understood what that meant. i am unsure of the depth of the pitting so i suppose it would be good to find that out from the machinest.
Is it highly recomended to run a set of new, say Eagle rods with the new pistons? Im really not planning on running a TON of power, but incase i change my mind i want to be safe.
But again, do i need standard bore head gasket, or should i get the appropriate size for my bore?

Find out the extent of the pitting before moving ahead with anything. If your machinist has to bore the block to .20 over you don't want to be stuck with a head gasket you can't use because it's for the stock bore. As far as the rods go, it all just depends on what you want to do with the car. Stock DSM rods have been known to push the 500hp mark so the stockers are plenty stout enough for most of us. If you decide to keep the stock rods you'll have to get a set of pistons designed for press fit wristpins or have the rods machined to accept locking pins. You'll come to find that your car will never be fast enough or have enough HP so it's best to carefully plan out a realistic goal and do your best to achieve it.
