replace all head studs, with ARP studs. and try to use there bolts and studs everywhere if you can afford to. they are among the best in the industry.

you can also get a Comp Cams Pushrod Length Checker.

and you can get a Stud Removal Tool . both tools are worth the money if you build more engines in the future.

it is a great idea to get the engine building book . they mention tools and how to use them in building an engine. lots of good usefull information.
