Aj, once again, thanks. But, this tensil strenght on forged piston heads, I dont understand it. Tensil strenghth is the strength it takes to pull something apart. Wouldn't compression strength be a more effective validation. What am I missing?

Anyway...I am debating wether or not to remove my car from the road and make it strictly auto-cross. I would like to crack the block and uprade the guts as well as compression. Why can't perfect timing be re-acquired after milling, isn't TDC TDC, does this mean to acheive perfect timing you would have to machine custom cam gears to make up for the gap distance between p/head and valve. Would the same apply to a thinner HG.

Forged pistons sound good, would you recomend a set? Pistons and connecting rods....should they be bought together?

Finnaly.....I live in Massachusetts, we are not known for our women, weather or race tracks. Anyone who reads this that is in the New England area, w/i 100 miles of Lowell MA, please recomend a decent race shop, we have a bunch of hacks in Lowell.

thanks DEV
