How do these patriots compare to Canfields and AFRs?
They are not of the same quality as far as components and materials as the AFR's are CNC ported and the Canfields are much larger 195 cc on the runners. These are a budget head for those looking to make big power gains for modest motors. These are not a fully prepped race head like the Canfiields or the AFR's but they are also several hundred less in cost so you can't complain. If you have $1400-$1500 for a set of heads, order a better head, but for $850 shipped, you can't go wrong.

it does sound like the better deal for those are wanting to buy gt40 heads and then pay to have extensive work done to them. so in the matter this does sound like a better deal for the buck

I am installing these heads on a 1979 302 plus.030. comp cam 292/560 roller rockers. trw forged 2488 pistons victor junior intake, 750 holly msd ign and dist.4:30 gears a c4 with 9 inch converter and brake. The car is an 87 that used to be a 4 cyl. 2 questions, I have a set of diamond racing pushrods from my old heads 6.875 .080 will these work? I am going to pick up a checker. The valves are .100 longer then stock. #2 I have a compucar bottle set up 50 - 275 hp. What do I do with my timeing. I'll start with the 100 hp jets. any help would be great Never messed with a bottle before. I am running a Barry Grant electric pump and regulator

will the 2.02 intake valves work on a stock 1995 short block or would i need aftermarket pistons? if they will clear the factory pistons what would the cam lift be limeted to?

Yall will have to check the PTV clearance yourselves, or whomever is doing the cam swap. He can give you an estimate, but its almost always different with every motor.

I love how the S197 owners on MF are known as retards.
I have a 65mm t/b,75mm maf,1.7rr,cold air induction,headers(not sure what make,bought it already on),h-pipe,2 chamber flow masters,373 gears on a 95GT. What would be the approx. hp gain with these heads. Does patriot have 165cc heads or would 185cc be better? Would this be a good idea to do a head swap with 118,000 miles on the motor?

First off there's alot of different ways to get to that power level pretty easy. We built a few 306's that will nearly hit that but it's safe to say a 347 would be a better street car for the 350-360 RWHP mark. You can get close with a 306 but i'll be a nasty, rowdy, hi compression, hi rpm set up to reach you goal all motor.
OR
You can build a mild 10:1 347 with the same induction (Alum H/C/I) and you'll be there all day long with a more streetable set up. Cost aside, the 347 will also be a solid daily driver. We've done several with mild TFS Top Eng Kits that all made 340-370 rwhp with a set of headers and good tune.
We have a motor sale about to begin for next months promo. Call or PM us for more details!

P.S. If you want to run these heads you'll need aftermarket pistons that have valve reliefs (FlyCuts) that will clear the 2.02 intake valves or you need to run a small cam like Steeda #18. With the smaller cam you'll still make good power and sound nice.

Thanks for the question Scott. The Patriots only come in a 185 config and they won't clear a stock shortblock unless you're carefull on the cam selection. Stick with a smaller grind like the Steeda #18 and you should be fine but ALWAYS check PTV! The original motor with 118k should be fine as long as it's running OK to start. You can also check compression to ensure it's still tight. Let us know if you need to know how to check it. Thanks!
wouldent the 347 be more likely to warp, or crack a block with the cylender walls so thin?
i like the idea of a 347 with a 150 shot, but im afraid that its to much spray for such a bored out block!
what are your thoughts on this?

I have another question about a misfire every once in a while. I put new plugs in along with wires, cap and rotor. A machanic tried to put it on a scanner & it wouldn't scan on his system. Do you have any ideas what it might be?

The cylinder walls of the block on 99.9% of all 347cid, specially in a stock block, are only .030" overbore. Where do you get your information of cylinder walls warping and or cracking the block. It's no secret what causes stock blocks to fail. A properly built 347 will handle a 150 shot on a block that's no more bored out than a 306cid engine.
