Hey I have a fully built Lt1 with 11.5 to 1 n/a and I have felpro 1074 head gaskets on it and run arp head bolts. How much nitrous would be too much for these gaskets? I run 150 now and want to up it to 200-250 and wanna know if it will be ok.. Any help or opinions would be great, thanks.

 

you should be a ok with those gaskets and bolts. just make sure your tune is on point.

 

As long as they have plenty of clamping force the felpros hold tons of power. We have nitrous guys and boost people making 8-900 on them.

 

i run 18psi on a F1a plus spray on 1074's... they take a beating!
