i ll be ordering the 12 bolt in a couple weeks,then its on for saving for new heads.my plans are a 355 s/c and id like to get the 195cc comp pkg afr heads.but i noticed they only have a small block chevy head and a lt4 head.Do they have a 195cc LT1 head design??i really dont want to convert to a lt4 if i dont have to.

 

They call the 195 an LT4 head because it requires the use of an LT4 intake manifold. There is really no "conversion" necessary other than using that intake in place of your LT1 intake.

 

yes i know this,i was jw if they had the 195cc head compatable with the lt1 manifold.

 

This should be discussed in LT1 Tech. Transfering, thanks.

 

I think the AFR LT1 are 190cc, not sure though

 

I think that's right. But I heard that AFR stopped making the LT1 version in favor of the raised runner LT4 version because no one was buying the LT1 head. Might not be the case though, easy enough to call them to find out.

oh ok,thanks for the info.i guess its just worth to upgrade to the lt4 style then.i dont really want anything under the 195cc head.thanks guys,i ll give them a call

 

why not switch to a lt4 intake?? doesnt it flow better, and its only like 300 bucks?? already spendin the cash might as well do it right the 1st time!

 

AFR made the 190cc and a 195 cc, the 195 was recomended for an LT4 intake, but an LT1 worked fine on em. I went with the 190s a few years ago (when running a 350) wish now I'd gone the 210s (now a 383). they no longer make the 190ccs for LT1s now they only make the 180cc for LT1 then jump to 195 , but again recomend the LT4 intake.

 

well i wanted to just hone out my intake but i guess i ll get the lt4 intake.whats the difference between the two intakes anyway?

 

The LT4 has more material to allow for a higher port head, and its powedercoated red...lol

 

so basically a honed lt1 intake and portmatched to the heads is just as good as a lt4 manifold?

 

No, the LT4 heads have a few tenths of an inch more material, the LT4 heads ports are higher. You could weld material onto the top of the LT1s ports to compensate, but unless you have the stuff to do this, it can be pricy.

 

Right, using an LT4 manifold on heads with LT1 intake ports or vv. is a bad idea. The ports will not line up. The LT4 ports are 0.100" higher.

ok then i guess my only option is going with the lt4 intake manifold when i get the 195cc lt4 heads.thanks guys
