Got a question for all you guruus.....
 

Okay I am a member of hondaswap.com and honda-tech also. I have asked them both the same question. I own a 90' CRX HF. As you well know that the head on the HF only has like 8 vavles. Well there was an article on hondaswap.com where they swaped the head from a D15B6 to a D15B7 and swapped the ECU, Intake manifold and tranny and said that they were able to get substantial gains from the swap. BUT! Honda-tech.com said that it wouldn't work that there would be valve collision and that it just wouldn't work! Some on honda-tech said that it would some said that it wouldn't. So I pose you now the same question.

like i told you on my board, Cory thompson made it- and ran it in a car. it works.

email chet, and he will get in contat with cory, who will confirm this as well.

Have you ever taken a motor apart?They have 4 releifs on the pistons,8,12,16 valve all the same,anyone that tells you that a 8 valve only has two per piston and a 12 valve only has 3 per piston is a ****ing retard.
