Thermoquad race tune

i loved my TQ when it wasnt leaking like a sieve, main well crossovers would always seep into the primary bores after shut-down. however when it ran right, it ran amazingly. currently i have a friend of mine who works at a custom plastic machining shop making a program on CAD to machine new main bodies. hoping itll turn out good so we can get the finished product underway. the problem is the material the factory used is wicked expensive and only available by the block. im talkin 3ft x 3ft x 2ft block....fingers are crossed though i have 8 of these things (all but 1 of the main bodies are cracked/burned/warped) and 2 strip kits that at this time are useless to me....
