I've been getting ready to do a rocker swap finding sources etc , and my question is can I actually just slightly enlarge the holes for the stud mount on roller rockers instead of swapping specialty 10mm to 3/8 studs or drilling heads for different size studs... 3/8 rocker holes are only 0.0187008 smaller than 10mm studs.

A lot of trouble to save $50.00. Just use the right studs and you will be able to use the polylocks that the rockers will want. Larry

50 bucks? , the 10mm to 3/8 are 100 bucks not including shipping. If it would work I don't see it being alot of trouble a 10mm drill bit to enlarge each hole doesnt take long at all. I would rather drill cheap ebay rockers than drill the heads and get me a completed roller rocker setup for 100 give or take. I'm just wondering if i'm missing anything to where it won't work.

Like Larry said, about $50: http://www.summitracing.com...p-100-7201/overview/

Well in that case I can deal with that , I couldn't find anything less than 100-120 with fierostore being the cheapest. extra 100+ bucks breaks the bank.

Just note rockers, if you're replacing them with 1.6 rockers, keep in mind they will add lots of wear to your cam. Most cam makers will void warranties if use gp form 1,5 to 1.6

thanks for the source, and thanks for the cam wear advise. I've already decided to not bother and save my money. Just find somebody that can give me a good tune with what I already have done.
