slow down guys lol

i know ET are the best but what i wanted to say

my car is 5.3 stock bottom so the et heads might flow so much that the 5.3 wont have the low end power any more

they worked very well in my brother car but it was 383 stroked ls1 with manual trans and big cam

bigger not always better in some cases

also am not throwing them if they wont work as well as they do on bigger cubes , then am gonna keep them for the project am gonna do (402 or 408)

 

another thing guys i asked about the numbers on heads because my brother dont remember the sizing exactly he said 225

does this numbers mean the size?
215.035.00

cheers

 

Call Cary @ http://www.perf-induction.com/ and he can tell you everything you need to know about those heads by the serial number.

 

thank you very much
