About how much will it be for a deck resurface and bore and hone?

This exact question came through the site last month, and it is the most common one we get about block work, so here is the answer we give at the counter with the math shown. Look up a price for this online and you find forum threads from fifteen years ago where somebody paid $35 a hole in 2009. Nobody charges that now. What follows is the 2026 number in Bowling Green, what moves it, and the one question that decides whether your block is worth cutting at all.

What does deck and bore and hone cost by engine type?

Total the two lines for your cylinder count and you have the number before you load the block in the truck. Every figure here comes from the published price list, and the invoice is written from the same table.

Add the hot tank and inspection, $50 to $120, because the block gets cleaned before it gets measured. If the mains took damage from a spun bearing, align honing is a separate $150 to $220 and it is on the ticket only if the bore gauge says so. A V8 with the full treatment, cleaned, decked, bored, honed, therefore usually runs $680 to $1,090 at the high end of the menu, and most daily driver rebuilds come in under that.

What makes the number go up or down?

Six things, and all of them are visible at the measuring bench before any cutting happens, so you hear about them first.

1. Cylinder count. Boring and honing is priced per hole. A V8 is twice the bore money of a four cylinder, every time.
2. How far oversize. A standard .030" overbore is the base price. Cleaning up a deep score or going .060" on a block that has already been cut once takes more passes and more time.
3. Torque-plate honing. Bolting a plate to the deck so the bores are honed in their stressed shape. Adds per cylinder. We recommend it on LS, Honda, and any engine with a thin-wall block or a race target.
4. Deck condition. A deck that is .003" out of flat cleans up in one pass. One that took a hard overheat, or that someone already decked, may need more off and a conversation about compression and head bolt reach.
5. Cleaning first. A block comes out of the hot tank before anyone measures it, $50 to $120 depending on size, and that line is on the ticket because grease hides cracks.
6. Material. Iron and aluminum cut differently. Aluminum decks need the finer finish an MLS gasket requires, which is a slower pass.

Is there enough material left to deck and bore my block?

Usually yes on a block that has never been machined, and that is the first thing we check because it decides whether the rest of the ticket exists. Two measurements answer it. The deck height gets compared to the factory spec, and if a previous shop already took .020" off, another cut can push compression up and shorten the head bolt engagement enough to matter. The cylinder walls get sonic tested or measured against the known casting thickness, and if a bore that is already .030" over needs .060" to clean up a score, a thin-wall casting may not have the meat for it. A small block Chevy or Ford Windsor with factory bores almost always has room. An LS, a late Honda, or a block that came out of a junkyard with an unknown history gets checked before anyone promises anything. When the answer is no, the honest verdict is a sleeve, $180 to $260 per hole, or a different block, and we would rather tell you that at the bench than after the boring bar has been through it.

Why does the deck matter if I only have a bore problem?

Because the head gasket seals against the deck, and the gasket you are about to install has a flatness and surface finish it will not forgive. Fel-Pro’s own surface finish guidance puts multi-layer steel gaskets at a much finer finish than the old composite gaskets tolerated, and a deck that passed in 1995 can leak with an MLS gasket today. If the straightedge shows the deck flat and the finish is right, we leave it alone and you save the line. If it is warped from the overheat that sent the engine in, decking is the cheapest insurance on the whole job. The decking vs boring article goes deeper on how the two cuts differ and which symptoms point to each.

How do I get the real number for my block?

Call, tell us what the engine is and what it did, and bring the bare block. The sequence is the same for a Corvette LS and a Massey Ferguson diesel:

1. You call (270) 438-4749 or send photos through the quote form. You get a menu range on the phone that day.
2. The block goes through the hot tank and gets a visual crack check.
3. Straightedge on the deck, dial bore gauge at three depths in each cylinder, deck height against spec. All of it written on a sheet you get back.
4. We call with the verdict and the firm number off the menu. Nothing gets cut until you say go.
5. Boring waits for your new pistons to be in the shop, because the bore is cut to the pistons you bought, not to a catalog size.

Industry practice backed by the Automotive Engine Rebuilders Association is to measure in and measure out, and the written sheet is what separates a machine shop from a shop with a boring bar. Most block jobs here turn around in about a week; harvest season farm diesels move to the front.

The rest of the block menu, sleeving and align honing included, is on the engine block machining page. Head resurfacing is priced separately on the cylinder head page, and if you are still choosing a shop, start with the questions to ask a machine shop.
