Your cam doesn't look bad for the time you have on it

The choice of what valve springs to use brings many questions to the front as there are so many varibles to consider---
You are looking for shaft rocker arms
You need to check for pushrod /intake manifold interferance where the push rods go thru the manifold by the intake ports---if they need some offset , you will need to take that into account when you make your rocker choice---also the under side of the rocker to valve spring retainer clearance--smaller diameter springs help in that case
You will probably want to run lash caps on the valve tips---Manley has a super set up fpr the retainer/lash cap and it would compliment there spring. Its called Loc-cap---
On aluminam heads you will need a hardened steel locator cup for the lower end of the spring--this will typically take up .060 of the installed height available, so it may be necessary to use some retainer or keepers that allow for extra height or to reduce it.


SOooooooo I guess you (and others) can see that its more of a question about the complete valve train than just a question of should I use this or that spring---
