If it were me I wouldn't even bother with 1.8 rockers go 1.95s with l76 springs or leave it stock. besides springs shouldn't be that much more to change once you have the old rockers off it's 1 minute to hook up an air hold 1 minute to pull the retainer 1 minute to replace the valve seal (which is a nice bonus) and just as long to put it back together, I think my whole set took about 45 minutes with 10 of that being looking for a retainer I dropped into a crevase.
