i have stock gt40 heads and i want to put some harland sharp rr's in them, but they only come in 3/8 stud, so is there a 5/16 to 3/8 stud conversion without drilling the heads?

Comp cams sells some. Why not use pedestals? They're plenty strong and stable, their only drawback is the small capscrew can pull out when you use aggressive cams with high spring rates. If you want to spend extra money, you could get a set of Jesel Sportsman shaft rockers that will bolt on to a factory head. I think they're around $650, but you'll own them for life and never have to worry about your valvetrain ever again.

which pedestals would you recommend? i have a 5.0 302, new 498/510 lift trick flow cam, new trick flow springs to match and a holly 750 carb, weiand xcelerator 7515 intake, stock gt40 heads, bored 30 over, h pipe with flows

Doesn't Trick flow sell some? Comp Cams, Crane(but they may not have the valvetrain stuff out now that they recently reopned). Do a search on Summitracing and filter through to pedestal, it'll list most of them.

converting pedastal to stud kits are a waste and have no added benifit cause the base where it screws in is still a 5/16 hole...just use pedastal

i found some ford racing full rollers on craigs list but kinda wary to buy them, he only wants 200 for a set that costs 349. still gonna check them out though
