I talked to TSP this morning and I learned that I was measuring the wrong spot on the piston to achieve the correct tolerance number. I'm going to try and explain this so it makes sense. As stated in an earlier post my pistons from a "net volume (-2.00)" are equivalent to a "flat" piston perspective. However, they do have valve relief and as such a section that is "raised" to compensate from a volume perspective. To measure the amount the piston comes out of the bore, I need to measure at the edge of the piston or the flat section on the other side of the valve relief - not the raised section. That would be important as I select the heads I use but based on my discussion with TSP this will not be an issue with the possible heads I may use. TSP also stated that once I choose the heads they would help me choosing the head gasket to achieve the proper quench and compression ratio I require. This company and the customer support is first rate. Based on that info I rechecked and the largest number was just short of .001.

I was measuring where the Texas Speed logo is printed.


That flat part adjacent to the raised, "TSP" part is what goes near the flat deck in the combustion chamber, making it the critical part to measure for clearance, quench, etc. If you look at the head, you'll see that the shape of that deck matches that on the piston. That raised part with the logo extends up into the chamber area to give you all that wonderful compression.

.001" out the hole gives you plenty of headroom to play with heads and gasket options. I agree with TSP's recommendation to decide on your heads first. They can crunch the numbers, including the valve events to suggest an ideal gasket thickness.

I ended doing a little clean up and adding another coat of paint to the oil pan. I then did two+ hours of curing at 200 degrees. It looks great. I will post a picture or two after installing it. Hopefully tomorrow. I ordered new crankshaft position sensor, camshaft position sensor, oil pressure sending unit, coolant temp sensor and oil quantity sensors. Still weighing pros and cons on the heads I will utilize on this build. Do I try to keep within my budget or just blow it all to hell at this point.

Did you go OEM on the sensors?

If staying NA, heads and cam are all where your power is. They should complement each other. How far you wanna go is all up to you. How many of these are you gonna build? If you do go all-out on this one and still end up building again later, it's likely the heads will be transferable to that build. Or an easy sell if not or not wanted.

Hmmm.. Trick Flow..

I am quite happy with my PRC heads from TSP.
