Default SBC 434 pistons for AFR 235 heads?

I'm putting together a 434 SBC 6in. Scat Stroker H-Beam Rods. Cola 4in crank.
400 mians. 2.100 rod journals. AFR 235's 70cc chamber. Demon RS 1025.
2in Custom anit reversion Spacer. Edelbrock Super Victor Fully ported by DR J performance. Custom 860 base Oregon Solid roller 4/7 swap. 316/322 670/640 with 1.5's 276/285@50 106ICL 110 lobe sep.
Looking for a flat top or a dish piston off the shelf.
Any suggestions?

AFR 227 235 heads take a custom piston, we can have any of the shelf pistons converted to accept the valve spacing. We do JE or Diamond customs for customers on a daily basis.

Give us a call and we can set you up

From the looks of you combination and depending on deck height, head gasket bore and thickness, and the valve relief depth your compression ratio is going to be somewhere between 11 and 11.5 to 1 with a flat top piston and even less with a dish piston. It looks like you have alot of cam shaft for your set up. JMO.

Default SRP or JE have no problems

For future referance the SRP flat top and dish had zero problems with Piston to vlave clearance. The JE dish no problems eithier.
To anyone wanting to know in the future. All off the shelf right out of JE Catalog.
