Question:

Chevy small block valve train ?

Ok guys I have a 70 4 bolt main 350 40 over. I have a lunati 292 cam 230 at 50 degrees. 480 lift. The kit says 1.5 rocker ratio. No valve adjustments needed. I just boight edelbrock aluminum heads summit number 5089 64 cc with 185 intake runner . And comp cam roller tip rockers. That say 1.52 ratio. All my decks on the engine and heads are stock not shaven. I have speed pro pistons with .125 dome. Im using standard felpro gaskets. Ok my question is will standard lenght pushrods work for this build. They are 7.794 length. And will my piston head clearance be ok cause of my domed pistons. and do I need to find rockers that just say 1.5 ratio to make this work or are 1.52 the same. Thanks

Answer:

Your fine with the roller tip 1.52's
Only way to be sure is to put clay on top of a piston and turn the engine over by hand and then measure the clearance on the indentation in the clay.
