Default 230/236 which springs

ive looked on different boards and nothign haven't seen a definate answer. i think comp recommends the 987 or 986 but they say the heads need machining. which springs should i go with

crane 10308 - heard the seats are just washers, need smaller valve seals, and use of L98 seats are recommended.

combonation motorsports ex-612 - heard they suck and are unrealiable.

918's is what im leanign towards. can these be installed on my stock seats? and which retainers and locks do i use?

918's whould be what I would recommend or 977's with Ti retainers if you want to do a dual spring.

also should i get 10* or 7* locks. whats the difference?

Springs like Heads aren't all about the "specs".....

A 987 is not close to enough pressure for any hyd roller lobe that plans on going over 6000rpm...

One way to get there.....

Installed height is usually the problem I run into on a LT1 head with a beehive spring.
