I have the casting number of 021.101.371 Q
From the best I can tell these are 914 1.7L heads, they have been converted to Hydro lifters. Is that right? Are these a good casting to run? Strengths and weaknesses? What type of Cam for these and Webbers? Whats the deal with the Hydro lifters these were solid lifter heads correct? Give me all your info need to learn. Thanks in advance. |

Headflow Masters in Cali can do a 42X36 valves and cleanup on them
for around 8 Franklins. AFA *restrictive*, it all depends on your engine's capacity, RPM range and driving style. I would ONLY spend the wonga and use a set of 2.0L heads for all out racing. 1.7 Q heads with FI rocks, as it is all about velocity and retaining the gas in the air! They also have the meat left in them to put a proper shape to maintain the fuel mixture, IF you know what you are doing... (IMG:style_emoticons/default/wink.gif) Smokey Yunick preached port velocity and maintaining homogenous mixture. YES, he is old school but his principles are what the car companies used to produce their newest designs(back then) with the most power and efficiency. Here is a GREAT writeup and discussion on the 1.7 Q heads: http://shoptalkforums.com/viewtopic.php?t=63224 I think Len is the best, most experienced T4 head guy around! (IMG:style_emoticons/default/smile.gif) Enjoy, it's 6 pages long and a LOT of info! That forums has pics of the different heads cut apart at the ports, showing both intake and exhaust tracts. Don |
