Got a 358sbc with SRP domed pistons, last year engine guy rocked the piston in the bore and measured like .016 out of the hole so he recomended a .051 head gasket. The clearance seemed right so thats what we ran.At $52.oo a piece. Then I found out that the piston should be measured flat in the bore, I measured the piston hieght during disassembly the other day and got about .005 to .008 ths. What would you recommend for gasket thickness?? running 6in crower sportsman rods 3.48 stroke turning 7-7500 max. Thanks alot for Your help Josh K.

If your running at .005"-.008" out of the hole, you can use a .041" head gasket with no problems.

i'm not steve, but......i've ran them as much as .010" out of the hole with a .042" gasket and have heard of others running as much as .014" out of the hole. .010" out and i was a little worried, but i ran it and it stayed together all season. if you ever beat a bearing out, it could be an ugly mess....but then again, when was beating a bearing out ever pretty?

You should retain a minimum of .030" piston to head clearance, provided you have a piston that is stable in the bore like your SRP. Just make sure the engine is good and warm before you race.
