I have a 95 h23 prelude, I just purchase a gude racing head with stage 2 camshafts,$500 upgraded valvetrain conversion, intake and exhaust port work along with three angle valvetrain job. The combustion chambers and the bowls have also been smoothed/blended along with shaved valveguides. I bought this off of someone on ebay it had been used for 10,000 miles then taken off due to the car being sold. So here is my question, the guy had 100% positive feedback so its not that I dont trust him, but I received the head today and it looks just like a factory head/cams, etc. Im not super knowledgeable in this area, but it looks pretty similiar to a stock setup. Is there a way by looking at this head and cams to tell if it is truly aftermarket parts and ported/polished head or not?
