resleeving and port/polish question

[darkerdayz]

first, the quesiton about resleeving.
ok, i called this machine shop in decatur, GA (the only machine shop i know of anywhere near this area) and i asked him how much he charges for resleeving. he told me that it was $300 + $27 per sleeve. when i asked him how much boost his sleeves could handle, he sounded like he was a bit confused. i went into telling him that i wanted to boost my engine. he then said that sleeves dont strengthen the block, they are really only made for if you want to run a bigger bore piston. he said that i would have to do other things to strengthen my block. i know quite a bit about cars and i've never heard this before. should be a word from the Man upstairs telling me to steer clear from this guy? what do you guys think? any help would be greatly appreciated.

now on to my second question.
i then asked him how much he charges for port and polish. he said that my best bet would be to instead of port and polish, i should match port it. i've never heard of match porting before so after he explained it, it sounded pretty good. this was for about $300. do you think that is too little? like i said earlier, i know most of my shit about cars, but i dont know what kind of prices that tuning cost. again, any help would be greatly appreciated.

|ps| can someone please explain what port and polishing is? i understand why you do it, but i dont understand exactly what the polish portion of it is for.

well if they sleeve the block as thy do with diesels then they dont know jack. sleeving is a skill they must learn. sleeving a Honda block i a close tolerance thing, too tight and they crack, too loose and they leak. do yourself a favour and send it to golden eagle. port and polish is a time consuming talent. which needs expirience with aflow bench and dyno, something they don't have. port matching is east, you can do it yourself, put the gaskets on thier place, mark thie place and cut away the excess metal. free power if you're careful

The guy works at a machine shop that probably deals with standard rebuilds not a performance shop. Everything he has seen or offers is probably for stock appilcations. Most sleeves are made for a bigger bore size. But, you can buy performace sleeves such as DART that can handle more cylinder pressure as well. The price of the head job is negotiable. Every shop has there own rate. Your best bet would be to find people who have done business with the shop and see if they were pleased or not. As for port and polishing the head, it goes like this. You port the head to allow a larger volume of air to flow through. Then the polishing is to allow that larger volume of air to increase its velocity. Think of it as throwing dish soap on a slip and slide. But, you don't want it polished to a completely smooth surface as you do need some turbulance in the air so it can properly mix with the fuel.
