I have a 355ci with a new stock spec crank and upgraded pistons. The pistons are flat tops with the valve reliefs. I have a howards cam 114lsa with 118/224 duration and a HSR with 30# injectors. The transmission is a 700r4 built with an EDGE torque converter (3000rpm stall).


SO, the question is, what heads? my budget is under 1200 more around 1000.

EST HP/TQ?

 

AFRs are right around 1200 and you really can't go wrong with them.

 

X2 and you should be looking at the 180cc intake runner size.

 

Where are you getting afr's for 1200?

Dart shp is closer to 1000$. The 180's are decent heads

 

Yea, AFRs for 1200 are too good to be true. Used maybe. I think I'll go with the SHPs. I'd be looking for the 65cc 180s right?

 

Are Pro-filers good? I see I can get them for a grand too and they have better flow numbers than the SHPs.

 

Pro filer is 10-20 hp better than shp's on a 450-500 hp engine

 

That sounds right up my alley. I'll order a set next week. 64cc angle plug 180s right? I don't intend on spinning past 6k as I have a stock 2bolt bottom end, though all of it is new.

 

Dart Pro 1's, RHS, and Profilers are my top 3.

 

Yeah 180's would be fine

 

Thanks Orr, You have be a huge help over the last few months. I have a solid plan and in the next few months the mechanicals should be done.

 

That a roller cam? If so get the dual spring option, should be 1.44" diameter springs

 

.

 

Yes, it is a hydro roller. I was going to order the 1.525 springs, pro-filer says they are good till .650. I'm only running a .495. (new lifters too)

 

Just make sure they arent solid roller spec springs. They will kill hyd lifters

 

This is what I have on the order form.

The order form has .650 lift, 1.525 dual hydraulic roller sprigs, AL retainers.

 

No info given on the spring specs that i could find. May ask pro filer what the pressures are to be safe but sounds like they will work.

 

For anyone else that are thinking about these heads and the general knowledge of people that read this:

I called pro-filer and they said their spring seat pressure is 130#/350# with a max lift of .650.

You can get them assembled and shipped to your door for around $1100.

 

For anyone reading this,take this info to heart.The castings imported fall apart,where the spec of concentric of the valve guide being in-line with the valve opening spec is by far from right.So sealing does become a issue.

 

Maybe you could reword this and then show this with a picture or article where it happened?

 

Yeah, what imported castings? Pro filer is usa made

 

The ref link:

And what we are finding in our engine building business.

 

Are you saying this is an issue you have seen with the made in USA profiler heads?

 

We sure ant seeing on AFR,Brodix,RHS

 

But like I asked before... Are you saying this is an issue you have seen with the made in USA profiler heads?

 

I would talk to pro filer directly and if you see a problem with the heads talk to them about it and they should replace them. However i have not heard any issues with pro filer.

Pro comp however have heard some issues

 

I have never hear of or seen issues with profiler either. That's why I was asking him to clarify.

 

If that is the correct link, and my browser followed it to the correct spot, That article had nothing to do with Profiler. So when you state a problem with profiler what are using as a base for your statement?

 

Reading comprehension 101:

"And what we are finding in our engine building business".

 

I can read and understand it just fine. You are the one who was talking about profiler heads and then referred to them as being imported with contradicts yourself since they are made in the USA. Which is why we all wanted you to clarify what you said.
So I will ask again. Are the made in US profiler sbc heads having an issue with valve guide to valve alignment?

I also have sent a message to Chad Speier to see if he has seen this in profiler heads. You would be hard pressed to find someone who knows more about profiler heads or heads in general.

 

Really trying hard not to come off as a smart bass,but not hard pressed as you might think.

Everytime you want to compare a part that they are as good as another brand name like say AFR's,well surprise it is the AFR's you needed to buy in the first place.Nothing is for nothing in this business and take this advise to heart.....the "deals" just ant.

 

AFR as good as they are are not without issues. All manufacturers occassionaly run into issues. Historically with afr, i have seen/heard posted that there have been issues with valve cover seal, oil drain back holes, and sometime cnc tool cuts in the port that should have been blended. Afr just has a decent customer service so they handle those issues

That being said i like AFR. Great street heads, perfect for hyd roller cars
