okay well heres the deal

i have a chance to get some holley sytamax heads.

that came off of a 351 And they only have 1000 miles on them

They feature 2.02 intake valves and 1.60 exhaust valves. Double Valve springs for

up to .600 Lift cam 3/8 rocker studs.The exhaust ports have been cleaned

up .They have also been milled .020 to get a 60cc combustion chamber .

Now would these fit or work good with a 306 SUPERCHARGED 94

AND WHAT WOULD BE THE BEST CAM FOR THIS SETUP

I think they would be a great head. They flow quite well.

Need to make sure the compression is not too high for the supercharger. The heads will make good power.

As long as the compression doesn't work out to be too high, and the pistons you chose for your 306 have larger than stock valve reliefs these would be GREAT heads to use.

My dad has ported and milled holley heads on his 302 and it makes 347rwhp NA.
