update.
stock ve head: during the process of removing the oem valve guides (to replace with the supertechs) 1 of the guides came out with a bit of the aluminum head attached. fahk, now a guide will just fall through the hole. we've been trying to find some oversized (outside diameter) guides to fit with little luck. the machinist contacted supertech who told him he'd have to order 100! even though the guides are actually made larger then milled down by them (st) to the required size! so we're at a standstill on the oem head for now.
ported head: if you look closely at the pics on post #947 you'll see that the OVERSIZED intake valves left witness marks on the pistons. the
92mm cp pistons valve reliefs were never opened up to fit the bigger valves when the engine was first built! hmm, fahking genius!
so, my new machine shop is gonna fly cut the reliefs of the 87mm cp's after he clays the head/block. needless to say all the intake valves need replacing.
we're also gonna pressure test the head. of course i hope the head test's good. if the fahker is cracked, the sleeved block may be a keeper. more to come...
new pic. all 4 pistons are identically hit. here's 1
