Need Help
I need some advice just to clear my brain.
I got a lt4 hot cam in my 1988 gta 305 5 speed
I just put in in on weekend...I took both heads off
im porting and polishing my lb9 heads they were awefull....
so much restriction raised casting marks they were the worst heads I ever did.
I still have one more head to do....
Here is my question.
I got new valve springs....
seat pressure is 110lbs open 325
cams in the 480-520 lift range max lift of .550
now I talked with them and they said it should be fine
I just want to make sure...
cam is 218/228 at .050 .492 .492 lift... with 1.5 rockers...
I got 1.6 aluminum roller rockers and I want to use them... so .525 lift on both...
will these springs be on with the 1.6 alum .525?
