I'm putting 351W heads on a 302. Comp flat tappet cam, new springs, lifters, chain, etc & a new Edelbrock RPM manifold. I bought the inserts to take up the excess head bolt space & I think I'm ready to go. Cam is in & I'm going to install the heads & get a length on pushrods - then get them ordered. I have a concern about water jackets & the maniflold mounting correctly. Anybody done this? Also - 164 tooth flywheel & aluminum bellhousing - every starter I look at seems to be $170+. Standard toploader 4 speed with this. According to the book, flywheel & bellhousing were meant for each other, but why so much for a starter??
