Once again, I need some help from you guys, as this hydraulic roller stuff is confusing me, and I have some questions that may seem pretty stupid.
I appreciate your help in advance, and am interested in your opinions. I just put the 89 318 302s back together stock, but I want to get the most out of these 308s on this 360. I have already cleaned up the bowls, tuliped the guides, and matched the ports.
1) Valve springs, I don't find much information about them. I go on Comp's site and it doesn't seem to spell out specific hydraulic roller springs.
If I am going to use a hydraulic roller, I want all the valve spring I can get. They used to tell you what spring goes with what cam, and I don't want to reuse the old ones.
Can I use my shorter Mopar Performance dual springs, that I have always used on 340s?
2) push rods, the stock ones are tooth picks. But due to the nature of the roller lifter, will a thicker pushrod run into interference with the large hole in the 308 head?
3) Rotators, why would I want to keep them? Makes me think I am working on a SBC. The exhaust spring is shorter due to them.
4) should I retain those huge/agressive stem seals?
5) Should I just drop the hydraulic roller and put a conventional cam in it?
