306 w/ frpp E cam and trickflow streetheat upper and lower, what would be the best heads for my setup without having to do anything to the pistons? And I also have scorpion 1.6 rr's to go with them

it depends on what horse power goal your looking for..and also is the car a daily driver? i have a 308 with edelbrock performer rpm heads with the 1.90 intake 1.60 exhaust valve with a 170cc intake runner..i drive my car daily but that will change soon..i picked these heads because with the smaller intake runner the car will make peak power where its good ont he street and not at 6500rpm lol

AFR 165's or 185's if you notch the pistons

I'd say AFR 165's.

yeah, it's a daily driver and I"m looking to make it around 300rwhp.I was looking at a set of patriot 185's

IMO, Trick Flow Twist Wedge, better valve train parts compaired to Edelbrock, and with the Twist Wedge chamber you can run a 2.02" valve with that camand haveno PTV issues (if the cam is timed properly)

Twisted Wedge are decent as well. I'd stay away from the Patriots though, they've had some quality issues.

i was going patriots also till i heard soo many bad storys...and i came across my eddys with dual springs..the valves were upgraded also..had port work and competition valve job from HBR performance..guy bought them for his 90 notch..but the car got stolen, for 700$ i couldnt complain

With the Valve train parts replaced that's a pretty good deal. I have a set of RPM's that I paid $1100 new and several months later I had to put another $500 in parts in them to make them right. In the end it was a waste of money for me, I would have been better off with a set of Canfields from Camshaft Innovations set up for my combination for less.

Assuming you have an aftermarket piston (aka, your 306), look for a cylinder head with a 2.02" valve.

Iprefer the new AFR 185cc heads, with the lightweight valvetrain/stems (8mm compared to stock style 11/32 on the other cylinder heads).

TW's are not to shabby either.
