I am in contact with summit racing also, they send to me a link with this kit for around 1600 usd. Did you pay also that?

Actually - I went with AFR 185's for like 200$ more.....I am going to go with some DART aluminum heads through the machine shop - I will have room to upgrade
I am going to talk tomorrow with Summit Racing to check the difference between the two 347 stroker kits.
Your basis is 302?
Really? From Summit racing? But the couple heads AFR 185 are much more expensive right?
I was not advices that she did - The person that I bought it from had done some frame work. Glad it wasn't an issue that needed to be brought up in the "assessment" discussion.
Hi bnero42,
I contact Summitracing and they offer my this kit: https://www.summitracing.com/parts/esp-b16422la030/make/ford, it is for two valves.
Your kit is for four valves right? (https://www.summitracing.com/parts/sca-1-94165)
If you install 4 valves cylinder heads, are you going to got more HP? Or what is the reason?
Where did you got your AFR 185 for 200 USD? It is used?
TIA

If I said 200$ I meant 2k - and
If I said 200$ I meant 2k - and my pistons have reliefs for 2 valves as are my AFR’s
Hi bnero42,
thank you for your answer. 2000 usd sound like I found in internet. Do you know maybe another cheap option, GT40 or GT40p will be a good idea? GT40p are easy to find here and around 250 usd.
Ok then you have reliefs for 2 valves pistons, but in the description from your summitracing link said:
Piston Style: Flat top, with four valve reliefs .

Flat top pistons with 4 valve reliefs mean that they can be installed in either orientation or side in the engine. Some pistons, domed pistons for example, can only be installed in one orientation. That's what the "4 valve reliefs" in the description means.

And do you have any suggestion of other more cheap cylinder heads that can be used for this 347?

I bought a Tremec T5 from Mustang T5 and a rear end 8.8" posi with a 3.73.
When you say cheap, what do you mean? How much do you want to spend? I don't think GT40P heads will do a 347 justice, so I don't think you'll get along well spending just $250 USD.
Cheap I mean maybe something from second hand, that I can use. I live in Mexico and I found for 250 usd a GT40p, but you have to rework it.
There aren't many options under $1000 USD. Your best bet is to keep an eye on your local classified ads, Facebook Marketplace, Craigslist, etc. You can try other sites like racingjunk as well, you might get lucky. But doing so you'll have to research whatever you find to see if it would even be worth buying for your application.
For the money and what they advertise for flow numbers and such, these don't look too bad on paper. Someone is using them in a build in the Fox section but I haven't heard how they're working for him yet.

There is also this set, but I'm not sure how well they'd support a 347.
Flotek has bigger heads, but those are their lowest priced. The bigger ones would probably work a lot better:
That's just what I can think of off the top of my head for low price points.
