Hey guys-- need a bit of help from you--- i recently swapped in a new b18b into my 94 integra--- wouldnt start-- after diagnosing it it had fuel and spark and timing was correct--- well yesterday i did a comp[ression check on it and it went like this 0-0-20-130 ---- i have already pulled the head b/c i believe it is due to bent valves--- how can i make sure my block is ok before putting new head on? thanks in advance
