BBC heads 990 rectangle port

looking for a pair of 6272990 BBC heads. square port, open chamber.

Those are HARD to find. What are they going on and what is the use going to be? Those heads are EXTREMELY too large for any kind of truck engine if that's what your plans are.
 
coolio. Yea, any truck of mine has a diesel in it. no worries there.

I picked up 2 holset HX35s and a C&S Specialties blowthrough converted billet Dominator 1050. sure I suppose I could drop 2-3k on wizzy aftermarket heads, but I though it would be cool to find a set of these.

So, theres a local engine guy that has a set of 990s. ported and ready to run. he wants $1200 canadian for them.

is that reasonable?

not really. the equivalent. edelbrock is the marine performer RPM-R very similar in chamber and runner. valve slightly larger. but that'll still run well over $2000 or 2400. up here. A guy offered me a set of AFR 325s they were still new not used yet, but still over $2500.


for $1200 ready to run and ported 990s will fit the bill I think.
