Its about $5 a lifter online ($80 a set...really?) , but if you can take them to a place, they may do it for less. There is a classic import shop here in So. Cal that will do it for $1 a pop but usually do older N/A Volvo and Porsche lifters. Oregon Cams does them (solid slants) too.
I reckon it would probably depend on how expensive the lifters were in the first place.. Oregon cam (in Vancouver Washington) it's just a short 10-15 minute drive away and I enjoy talking to Ken the owner.. nice old school cat...
