Many thanx Zippy!
Not really a Zombie yet, just dead from the head down from a year of isolation...
The problem is buying stuff in singles 'as and when you can afford them'.
Should always save up faster and buy a PAIR of heads so if they have issues then they both have issues...
Got a pile of wrecked hemi stuff here that I've collected for 35 years from failed projects and loose rod bolts etc...
Anyways, folks who venture into the mysterious world of 'Hemi', please expect to be 'poor and puzzled' with equal amounts...
I know I am, I spent more on two HEMI heads and valve gear than I spent on whole 440 engines...
