A printable checklist for the parking lot. Ask these before you sign the work order. The right answers keep your bill predictable. The wrong answers tell you to get another quote.
Ask each question. Listen to the answer. Compare it to the "good answer" in each card. Any shop that gets defensive about these questions is not the shop you want.
This is the most commonly hidden line item. Resurfacing the cylinder head costs $200 to $500. Some quotes leave it out and add it later as a 'discovery'.
Good answer
"Yes, it is included. Here is the line item showing $300 for the head shop work."
Red flag
"We will see if it needs it once we have it apart."
Most modern engines use torque-to-yield head bolts that stretch on first install. Reusing them risks the gasket failing within months. New bolts cost $50 to $150.
Good answer
"Yes, new OEM bolts come with the gasket kit and are torqued in factory sequence."
Red flag
"Only if they look damaged."
These parts are accessible during the gasket job. Replacing them now adds $50 to $150 in parts and 10% more labor. Doing them later as separate jobs costs $500 to $1,000+.
Good answer
"I always quote them as part of the bundle. It is the only sensible time to do them."
Red flag
"We can do that as a separate job later."
Sometimes the head is cracked or warped past machining. A replacement head adds $400 to $1,500 in parts. Confirm the head can be saved before agreeing to the labor.
Good answer
"Based on what we have seen so far, the head should be salvageable. We will confirm at the machine shop and call you if not."
Red flag
"We will not know until we are inside."
There are several tests. Symptoms alone are not a diagnosis. A shop that diagnosed by feel may be wrong, and you do not want to pay $2,000 for a gasket job when the issue is a $200 thermostat.
Good answer
"We ran a block test and a compression test. Both point to gasket failure between cylinders 2 and 3."
Red flag
"It is overheating and losing coolant. Definitely the gasket."
Standard is 12 months or 12,000 miles. A shop that only offers 30 days or no warranty at all is signaling low confidence in their work or in the parts they use.
Good answer
"12 months, 12,000 miles, parts and labor. Written on the invoice."
Red flag
"It is good when it leaves the shop."
Reassembling a warped or cracked head guarantees the new gasket fails. The check takes 10 minutes at the machine shop with a straight edge and a pressure tester.
Good answer
"Always. The machine shop verifies flatness and pressure-tests for cracks before we touch it."
Red flag
"If the head looks fine we can skip the machine shop to save you money."
OEM is best, premium aftermarket (Felpro, Ishino, Stone, Victor Reinz) is fine, no-name budget aftermarket is a redo waiting to happen.
Good answer
"OEM Honda gasket set. Or Felpro Premium if you want to save $30."
Red flag
"Whatever the parts store has cheapest."
Smart shops note everything they see during diagnosis: a leaking valve cover, a worn motor mount, a rusty exhaust. You may want to bundle these.
Good answer
"I noticed the valve cover gasket is seeping and the lower radiator hose is bulging. I can include those for $200 in parts and another hour of labor."
Red flag
"Just the head gasket."
An honest shop will keep the old gasket and show you the failure point. This confirms the diagnosis was correct and gives you peace of mind that the work was done.
Good answer
"Of course. We bag the old parts and give them to you with the keys."
Red flag
"We dispose of those right away."
Mid-job discoveries are real and can add $500 to $2,000. You want a written commitment that the shop will call you before authorising extra work, not just hand you a bill at the end.
Good answer
"We will stop the work, photograph what we found, call you, and walk you through options before charging for anything additional."
Red flag
"If it needs work, it needs work. We will sort it."
Set expectations early. A reasonable answer is 3 to 7 days for a 4-cylinder, 5 to 10 days for a V6, longer if the machine shop has a queue.
Good answer
"Plan for 5 days. We will have it back to you Friday assuming the head shop turns it around in 48 hours, which is normal for them."
Red flag
"Hard to say, could be a couple weeks."
