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.

no truck engine. my Z-28.

Whew, was going to say those heads flow at the high rpm level. I'll keep an ear open as i know a few people who do come across them from time to time.

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?

Good luck would it be better to look at some edelbrocks

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.
