Post aftermarket head gaskets
OK so heres my dilema now.. I just had my heads decked to 50 thou. Ready to assemble so i go to order the coper gaskets that everyone tell me i have to have or the stock ones will blow. Well the guy at flat out gaskets tells me the compressed thickness of the copper gasket is 40 thou. this means i just spent 400.00 to essentially run heads performing at 10thou. well the guy tells me they have a lead gasket and that thickness is 30 thou. still.. ill only be performing at 20 tho. Anyone have any advice? this is begining to be a pain in the ass..

do you know the compressed thickness of the stock ones? and have you had a problem with them blowing?

I went copper when I put my heads back on... They leaked. I thought maybe when the heads were trued up, they didn't match the block anymore. Anyone ever heard of that happening?

When I did the first cam we put stock in ,heads decked 50 thou. They were leaking with in 10 hours. I put the copper in no problems, I decked the block 10 because it was not flat. 50 off the heads, 10 off the block, compression is up to 240 now that the rings have seated.

put da stock gaskets in..... I've got over 800 hrs. on headwork & stock gaskets. If da gaskets fail, it ain't from da headwork.

I have a gasket kit for the briggs 35 in you are interested. I screwed up when ordering and ended up with two extra sets. One kit includes 2 head gaskets, 2 valve cover gaskets , 2 exhaust and 2 intake and 4 valve seals. Basicly everything u need to redo your heads. The kit is direct from briggs all oem stuff. Let me know if you are interested.

I have 100hrs on the copper ones and haven't had a problem. I did hear yesterday second hand that EVT stopped offering the copper because of excessive failures.

Wouldn't call it excessive but there were some failures. The new gaskets we have cured that problem. They compress to .040".
