Strokers and standard displacement engines have the same problem.

Another point of information here. My engine builder used the hyper pistons also, not sure about the brand. He specifically told me "do not build a fire in this engine without letting it get up to operatin temp". Now I know why he stressed this point.

Head Casting Numbers???
BTW >>> What are those heads ... really? They do look like vortecs ... but they seem to have an exhaust xover port. & Just because they may have 4 mounting bolts per head does NOT make them vortecs.
How about look for and post all head casting numbers ... maybe these are not even GM ... maybe aftermarket-sorta-vortec-kinda-knockoffs ... dunno ... post numbers please.

As I dont think i can attach pics yet, here is link. On my 97 LT1 the passage circled in red was blocked off by the intake gasket. Scrapping the gasket off it appeared to be a water passage. If I am wrong educmacate me

Let me try again.....the ony place that sealed off port is open to is the valley. Nothing else. There is no port on the intake there. It's nothing more than a part of the valley.

Almost looks like something was hitting the face for a very short time, ie: part of the piston? Which is MIA.

Ok I did a search on that head and gaskets and came up with this.
http://www.sallee-chevrolet.com/fram...ds/Vortec.html
If you look up the part number for the intake gaskets you get 2 different ones. First one 89017465 GM Intake Gasket. [Old P/N 12529094] is what is installed on this engine. The second one 1255 Fel-Pro Intake Gasket is different. If you notice the passage I am talking about would be blocked by the intake but sealed by the second gasket.
Ok I am done
