TEA stage 1.5 5.3 heads vs TSP PRC stage 2.5 5.3 heads I have been looking for some heads to go along with a cam i picked up (228/229 .591/.591 112lsa) and everyone is saying that 5.3 heads will work really well with the cam, so i have been trying to decide between the TEA or the TSP heads...both have similar intake flow numbers but as far as exhaust flow numbers the TEA heads flow much better and they only cost $300 more, also everyone that has had the TEA heads say that they are awesome heads. The TSP heads are new but so far they have been producing some decent numbers from what i have seen. So which ones do you guys think are better and why??
I went with the TEA 1.5 heads and a Futral F 4 cam,3200 vig,3.23 gear,car went a 11:50 @117.I built a forged 347 but kept the heads.

TEA uses a different style flowbench.This is the reason for the elevated exhaust flow numbers.If flowed on the same bench at the same time,the PRC heads would outperform them.IMO,PRC offers the best,most modern heads in the market.

TEA uses a different type of flowbench audie technologies vs. superflow.This where the difference is.If you flowed the TEA head on a superflow it will not flow what TEA advertises for their bench.Not that it is wrong,for a true comparison you would have to flow them both on the same bench at the same time.

Both brand cylinder heads work really well! I think your best bet is to spend some time in the dyno section. The PRC cylinder heads are completely cnc ported & cnc valve jobed to make sure the product repeats what it's suppose to flow everytime. This way one guy doesn't get a special set while the everyday guy gets something else.
If you guys are ever in the area come by & checkout the Newen seat & guide machine at work. The beauty & consitancy that this thing busts out constantly amazes me!

My point being is still the same.Advertised numbers are from the company advertising their product.If a person wanted a true comparison,It would have to take place on the same type of bench,at the same time,with the same operator.
