I HAVE 95 GSR BUT THE BOTTOM HAD A HOLE, THE HEAD IS STILL GOOD, SO I WENT TO BUY A LS SHORT BLOCK, I'M TRYING TO HAVE THE CAR RUN AGAIN WITHOUT BUILD. SO MY QUESTION IS DOES THE GSR HEAD BOLT RIGHT ON THE LS SHORT BLOCK WITHOUT MOD? OR I HAVE TO RETHREAD THEM TO FIT?
THANK YOU

Block Modifications
Before bolting down the new head, a few modifications NEED to be made to the block. Normally, on a VTEC engine, oil is fed to the VTEC pressure switch by an orifice on the deck of the cylinder head matching up with a corresponding hole on the deck of the block. Since the LS has no such hole, and you want VTEC to work, you need to be creative.

 

All B-series VTEC ECUs will require you to use a knock sensor. Unless yours was reprogrammed to not look for one, one will have to be retrofitted into the block since there aren't any provisions for one on the LS. Some non-VTEC engines have a blank spot on the rear of the block where the threaded hole would normally be drilled on a VTEC modelIf you're lucky to have this blank spot on your block, use a 10.9mm bit and drill a hole deep enough to run a 12mmx1.25mm tap through it a few turns. For those not so lucky you'll have to either find another spot on the block where a hole can be drilled or have your ECU reprogrammed. Throwing a knock sensor malfunction code automatically disables VTEC. With our Civic, a Hondata-modified ECU was used, which did not require a knock sensor. The Hondata unit will also allow us to extract additional horsepower from the engine later on, thanks to its fine-tuning capabilities
