Another Head Thread, but with a stock cam
Howdy gang...
I need to pick your brains...
Well I dont know what it was, just blame it on the email gremlin, but I lost a nice deal on a set of Brodix Aluminum AI heads. From what I found out these would have worked nicely with SR manifold I am purchasing. Now I am looking for another set of heads though, hence the post in the parts section http://forums.corvetteforum.com/show....php?t=1605960
I need to keep the stock cam because of those wonderful Kalifornia Air Natzi's, but now need some idea on what other heads would work nicely with a SR.
Looking for something that would provide some nice flow for other Mods down the line, but still provide a nice increase for now.
This is all in and around a 85 L98 Engine.
Come on all, need some input...

A 180 or 195 AFR head would work great . As well as the 180s flow and your need for a smaller cam I wouldnt go any bigger. You CAN run more cam and still pass Kalis smog. With good heads and an intake, Id highly recommend it.
A 256 Voodoo cam from Lunati, Lingenfelter 211 or 213, there are plenty more to choose from, dont sell your power potential short if youre spending money.

I did not look at AFR heads and had forgot about them. Sometimes i need a good 
on the head to remember. Thanks for the reminder. 
Looking now and the 180's with the 68cc chambers look good. Was also looking at the Edelbrock 6087's (or similar), but now to find a pair from somebody.
Any other suggestions ???

Unless I really screwed up my math, which is possible, my calculations put the compression just below 11-1. Cant find the sheet I did it on but I think it was 10.8xx-1 which was manageable on premium pump gas.
Was I incorrect???

You don't "need" to keep the stock cam, as the smog ***** can't actually check it.
I have a friend with a SR 350 who passed with the LPE 219/219 cam, but just "barely" (AS&M did his tune), though the LPE 211/219 cam would pass no problem with a good tune.

For what it's worth, I installed the 70cc Edelbrock Performer heads on my '85 Corvette, with Edelbrock Hi Flo lower, roller rockers and stock cam. I easily passed California smog. Plus, I could run more timing (11 degrees) and it has never pinged even with hot weather last summer running over 200 degrees. I think the 70cc heads increase the compression ratio from 9:1 to about 9.7:1, but you may want to verify that. The heads and intake really gave a seat of the pants increase. If I had to do it over, I would probably go with AFR. At the time I felt it was overkill for my setup and didn't want to wait to get them. Actually, if I had to do it over I would just get a 383 and do an engine swap. It probably is just about the same amount of work as doing those heads.

agreed,
if your going to do heads and intake no reason not to do the cam. I remember reading awhile ago that some TPI guys actually went with a LT-1 cam and picked up some nice HP, plus they are dirt cheap. I'm not sure of the specs though. Maybe get whomever does your PCM to give you 2 tune proms so you can swap to a smog tune in a pinch
I'm pretty noob when it comes to TPI cars though and maybe you can't just swap out the prom on some years. I know on my newer cars it's just flashing of the pcm, whereas on my old stang I actually had different prom chips to swap out manually!
thx

I got to thinking about the age of the car (86) the mileage (72,000) and what affect raising the CR would have ie. hard on the rings, running hot, etc. I still have not bought new heads but was thinking when I do, I would shoot for 64-68cc heads, just to be on the safe side.

But the real question I have for any Kalifornia members out there is; if you are running a cam what kind is it?
