well its a short block i bought and while its out it seems like a good idea. i was told it has 50k on it but i want to make sure its fresh and reliable. the heads are already done it just seems like a good idea to refresh the bottom of it.plus im putting in a cc306 and need the extra insurance. im using high lift springs too and need to know if i can get away with the stock retainers.


thanks

yeah you might as well go ahead and refreshen it while its out if you have the money

and if you have the cash to do that why skimp on the retainers for the springs why not go ahead and get a new set while your at it they arent that expensive

Well, most stock valve spring retainers are made to be used with valve spring oil shields. If you don't use the shields the stock retainers are to small and don't fit the inside dia. of the aftermarket spring. This will allow to much clearance between the sp. and retainer allowing the spring to move around. Most aftermarket spring setups don't use the sp. oil shields so its always a good idea to buy the retainer thats made for that sp.

you'll have a hard time using stock diameter springs let alone the retainers.

Valve springs and 10 deg. locks from AFR 195 heads, ...would these work? they are the same srings that they sell to go on a lt1 head Here's the specs on the springs straight from the AFR website.
1.450" OD Hydraulic Dual Valve Spring, 120 lbs. on seat, .550" maximum lift.
I'm not sure how big my spring pockets are on a LT1 head but there are the
facts from AFR. but not sure if that helps.

Well, the dia. of a stock sp. is 1.250". What are the spec's of your Comp Cams 306?? Is this a hdy, solid or a roller cam?? What is this eng. going to be used for?? With a seat pressure of #120 what is the over the nose pressure?? If you are going to use this set up for the street your over the nose pressures should not be over #300 for a flat tappet cam to get a reasonable life out of that cam. If its a roller there should be no problem.
