Post small block heating up... need help

i am no where near being an experienced mechanic, i probably have no business under a hood... my concern is that i recently changed the oil on the sb and replaced hedder&collector gaskets and the engine was running fine till i scraped the asphault with the driverside hedder and since then the "idiot light" has been reading HOT... the car has been tuned up. what might have the hit shaken up? why does it read HOT?

also i have a problem with exhaust seeping in to the cab? i have a glasspack that ends before the rear... would i just need to put tail pipes?... will the tailpipes restrict the performance?

im quite certain that these are silly questions but i am new to this, as of 3 months ago i had never even seen a chevy engine. i appreciate all the help ive been given so far.

The coolant temperature switch is located on the driver's side cylinder head between Nos. 1 and 3 cylinders. See if the header has bumped the switch or the lead wire has grounded. You might simply need a new switch

As for the exhaust fumes, it is either coming from the headers or the lake pipes. If it is a passenger car, you need tailpipes.

Just think of it this way...everytime you investigate and repair something, you gain knowledge.
