Stock Block series

you can make them pull a cylinder head and CC the ports, same as in stock and super stock racing. once the rules for inspection and tear down are established, then guys won't cheat. you make it tough on them if its illegal. it only takes one guy to get booted out, rest will follow rules then. another way, is to make everyone show up at first race with heads in trunk, do a CC test, have them install heads and seal the heads to block. NHRA does this to get reinstated after failing tear down. pretty simple.
