Turbo head build

9 psi over 2.06 inches is only 18 lbs. Dont think its going to affect your slant springs 62lbs closed sealing potential. Run any more boost than 9 and you'll need some more work elsewhere. If you got the springs already, go for it for peace of mind.

318 springs are basically slant six valve springs, they will fit your stock retainers. RockAuto would be a source to check. You can also watch on eBay.
Are you planning on building your own manifolds?
Gill Welding has some neat stuff for the slant six. Google that. Also look over at www.slantsix.org lots of turbo builds over there.

thats why i plan on getting the 318 springs. i read that with the 340 prings and the stock cam you risk shearing a lobe off. The reason for replacing them is mainly for peace of mine and that my springs are old and might have lost some of there presure.
