Valve Springs & Roller Rockers
 

Which valve springs and roller rockers should I get? Will 1.72 roller rockers fit under stock valve covers? Is there 1.7's that will fit? I won't be getting a cam or heads or intake so the valve lift won't be a question, atleast not anytime soon. My valve springs are probably tired because I feel a drop off at the higher rpm's, and I am getting a new fuel pump since this one whines so much now (I know, that may be my problem). Also, how difficult are they to install and how much would it probably cost if I took it somewhere? I know valve springs are like $75 and rockers are $250 or so. I will be adding a supercharger eventually, there are just other mods to come first.

The roller rocker install is a piece of cake... The valve spring install requires removing the head (that's the way i did it)

Price wise. The rockers seem to be a dime a dozen on the web. They sell for between $100 and $125, as a mater of fact i have a set of them laying around, if youwould be interested in them drop me a line. Also, The springs, sell new for about $107 with the locks and retainers and should eliminate valve float, allowing you to turn the motor to 6000 rpm's

Do you have to remove the head? If I do that, I might as well put on a new set of heads and valves while Im at it.

You do not need to remove the head to change rockers and springs. You can buy spring compresers for the head on or off the block.
