finally installed the ported and polished heads on the hawk (did the tr224-112 last week) to raise comp to 11-1, the heads were milled .045 i used the stock pushrods but now i have a misfire (no codes) above 4500 rpm i'm sure this is caused by the length being wrong. i was going to go get some 7.350"s to see, but would appreciate any input. thanks in advance. jeff <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />
