Total Engine Airflow - LS2 Head work & Fast turnaround!

Well I have to give huge props to Mike at Total Engine Airflow for getting the work done on my heads extremely fast. He had mentioned about 2 weeks and when your dealing with car parts its better to err on the side of it taking longer than expected rather than get your hopes up.

Well being pleasantly surprised is always a good thing with your car. They had the heads for maybe a week and called me this morning to say they are done!!! Thats great news.

I had them take my LS2 heads and do thier Stage 2 work on them with my cores. Bang for buck it looked hard to beat for what the heads were capable of after the CNC job. $1360 shipped back to me I can't beat that.

The combustion chamber I had them go with 65cc and a 4.000" bore to match my LS2 block. They will be going on my stroker so one piece is already done.

The peak numbers he said at .600 lift (which is all the higher my cam will be going) were:
Intake 325
Exhaust 262.

Better than advertised so i can't argue with that.

Can't wait for the full engine build, i will post way to many pictures when my car is finally back together and running.

Sweet-

When you get the heads, post some pics and be sure to post the flow chart. I would be curious to compare them (flow chart) to my last set of TEA 243's.

Shall do, Looking forward to getting them back and see what they look like.

Many think they won't be quite enough for my 403 stroker, but I guess only time will tell.

I see it both ways but a cylinder head flowing 325 cfm is a great head. Could you make more power with an aftermarket casting, maybe so but at what cost per hp. You'll be happy I'm sure-

TEA is awesome. Any truth that Brian Tooley is retired?

What is the resulting intake runner size to get 325cfm out of a 243 head? I remember MTI getting 340cfm but they hogged out the intake runner to 240ccs and those heads lost power. Aintqik got 460rwhp on his 403 with a 236 XER cam with MTI stage 3's. CFM doesnt = HP when its coupled with huge runners. This is why an AFR 205 which flows 305cfm will stomp a 260cc LS3 head that flows 332cfm.

Too bad there isnt a velocity spec to directly show why. High velocity with lower advertised peak CFM will beat a lower velocity higher peak flow head.

They were a 225cc intake runner, or at least advertised that way. I think to match my 403 stroker its a good balance hopefully of velocity as well as a large enough plenum.
