Really we're not veering off course. The OP has an 85 car, I also have an 85 car. the 85's came with cast iron heads with a 73cc chamber @ 9:1 compression. The Op is asking about putting the 113 heads with a 58cc chamber. The cars with the 113 head I believe had dished pistons to keep compression at 9.5:1 where as our 85's have forged flattop pistons with big chamber @ 9:1 compression. All I was saying was to make sure that you have enough vavle clearence with the smaller chamber and flattop pistons if you're going to run 1.6RR, but also to make sure you have clearence between piston and valve either way the OP goes. The OP may need, as well as myself, to use a thicker head gasket, even the quench might be bigger, he(we) are also increasing compression ratio by quite a bit with changing to the 113 casting heads from the later L98 cars. No if there is not enough clearence between piston and valve and the touch, the OP my not be happy with the information he got here in the forum saying that it will be okay, I'm just saying to make sure the OP looks into that aspect of it. The information I have been given was that it should be no problem. Since I really dont KNOW FOR SURE, I am slightly hesitant to just throw the 113 heads on my car, as I do not have cash laying around to start from scratch. |
